ICL7621AMTV amplifier core information:
The minimum operating temperature of ICL7621AMTV is -55 °C and the maximum operating temperature is 125 °C. Its peak reflow temperature is NOT SPECIFIED Its maximum average bias current is 0.004 µA
How to simply check the efficiency of an amplifier? Looking at its slew rate, the nominal slew rate of ICL7621AMTV is 0.16 V/us. When the op amp is used in closed loop, at a certain closed-loop gain (usually 1 or 2, 10, etc.), the frequency when the ICL7621AMTV gain becomes 0.707 times the low-frequency gain is 480 kHz.
The nominal supply voltage of ICL7621AMTV is 5 V, and its corresponding nominal negative supply voltage is -5 V. The input offset voltage of ICL7621AMTV is 3000 µV (input offset voltage: the compensation voltage added between the two input terminals to make the output terminal of the operational amplifier 0V (or close to 0V).)

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Long term offset voltage stability will be degraded if large input differential voltages are applied for long periods of time.
2. The outputs may be shorted to ground or to either supply, for V

Care must be taken to insure that the dissipation rating is not
exceeded.

Application Information
Static Protection
All devices are static protected by the use of input diodes.
However, strong static fields should be avoided, as it is
possible for the strong fields to cause degraded diode
junction characteristics, which may result in increased input
leakage currents.
4-layer structure has characteristics similar to an SCR, and
under certain circumstances may be triggered into a low
impedance state resulting in excessive supply current. To
avoid this condition, no voltage greater than 0.3V beyond the
supply rails may be applied to any pin. In general, the op
amp supplies must be established simultaneously with, or
before any input signals are applied. If this is not possible,
the drive circuits must limit input current flow to 2mA to
