The units may be fully compensated with the addition of a 30 pF capacitor stabilizing the circuit for all feedback configurations including datasheey loads.

Leads having a maximum diameter. The product may be measured by direct methods or by gauge.
All leads — increase maximum limit by. The manufacturer’s identification shall not be used as pin one identification mark. The minimum limit for dimension “b2” may be. Dimension “Q” shall be measured from the seating plane to the base plane. This dimension allows for off-center lid, meniscus and glass overrun. The basic pin spacing is. Applies to all four corners leads number 1, 4, 5, and 8.
All leads — Increase maximum limit by. Applies to all four corners leads number 1, 8, 9, and Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury of the user.
A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. All types are available with B military screening. The inputs are shunted with back-to-back diodes for overvoltage protection. Therefore, if a differential input voltage in excess of 1V is applied between the inputs, excessive current will flow, unless some limiting resistance is provided.
Input Offset Voltage 0.
Input Offset Voltage Drift2 1. Guaranteed by input bias current specification. It is suggested that board leakage be minimized by encircling the input pins with a guard ring maintained at a potential close to that of lm335 inputs. The LM series has very low input datwsheet and bias currents; the user is cautioned that printed circuit board leakages can produce significant errors especially at high board temperatures.
R1 Figure 3. Offset Adjustment for Differential Amplifiers Figure 4. Do not short circuit the strobe pin to ground—drive it with a 3 to 5 mA current Instead.
If the strobe and balance pins are unused, short them together for maximum AC stability. Input Offset Current vs. Common Mode LImits vs. Equivalent Input Offset Voltage vs. Response Times Figure Short Circuit Current, Power Dissipation vs. Operation from split power supplies is also possible and the low power supply drain is independent of the magnitude of the power supply voltage. However, a large amount of crossover distortion may occur with loads to ground.
An external current-sinking resistor to -VS will reduce crossover distortion. There is no crossover distortion problem in single-supply operation if the load is direct-coupled to ground. Destructive dissipation can result from simultaneous shorts on all amplifiers. This input current will only exist when the voltage at any of the input leads is driven pm353.
It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip.
This is not destructive and normal output states will re-establish when the input voltage again returns to a value greater than 0.
This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. The input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0. Due to proximity of external components, ensure that coupling is not originating via stray capacitance between these externall parts. This typically can be detected as this type of capacitance increases at higher frequencies.
Destructive dissipation can result from simultaneous shorts on an amplifiers. Output Source Current Figure 4. Current Limiting Output Current vs.

Mold flash or protrusions shall not exceed. Terminal numbers are shown for reference only. Symbol “N” is the maximum number of terminals. Applies to all four corners leads number 1, 7, 8, and Intended for single supply applications, the Darlington PNP input stage allows them to compare voltages that include ground.
The two stage common-emitter output circuit provides gain and output sink capacity of 3. The output collector is left open, permitting the designer to drive devices in the range of 2V to 36V. They are intended for applications not needing response time less than 1 ms, but demanding excellent op amp input parameters to offset voltage, current and bias current, to ensure accurate comparison with a reference voltage.
It is due to the collector base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. This is not destructive and nominal output states will re-establish when the input voltage, which was negative, again returns to a value greater than This current is essentially constant, independent of the state of the output so no loading change exists on the reference or input lines.
The response time specified is for a mV input step with 5 mV overdrive. For larger overdrive signals ns can be obtained. See Typical Performance Characteristics section. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common mode range, the comparator will provide a proper output state. The low input voltage stage must not be less than Supply Voltage 10 Out of Saturation 1.

Life support devices or systems are devices or 2. A critical component is any component of a life support device or system whose failure to perform can systems which, a are intended for surgical implant into be reasonably expected to cause the failure of the life the body, or b support or sustain life, or c whose support device or system, or to affect its safety or failure to perform when properly used in accordance with instructions for use provided in the labeling, can be effectiveness.
Specifications may change in any manner without notice. Preliminary First Production This datasheet contains preliminary data, and supplementary data will be published at a later date.
Fairchild Semiconductor reserves the right to make changes at any time without notice in order to improve design. Obsolete Not In Production This datasheet contains specifications on a product that has been discontinued by Fairchild semiconductor.
The datasheet is printed for reference information only. It consists of four independent high-gain, internally compensated, low-power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar operational amplifier. In addition, the total supply current for all four amplifiers is comparable to the supply current of a single type op amp.
Other features include input offset currents and input bias currents which are much less than those of a standard Also, excellent isolation between amplifiers has been achieved by independently biasing each amplifier and using layout techniques which minimize thermal coupling. Short circuit to ground on one amplifier only. Guaranteed by design but not tested. Positive Current Limit Output Voltage vs.
