The AMSOP-07 is a precision operational amplifier with a very low input offset voltage. This device features a wide input
voltage range of
±13V
minimum, low input bias current, high impedance, high CMRR, excellent stability of offsets and gain
over time and temperature. Excellent linearity can be maintained even at high closed-loop gains.
Low cost, low noise, low offsets and high open-loop gain make the AMSOP-07 an excellent choice particularly for high-gain
instrumentation applications. Other applications include precision data acquisition, precision integrators, threshold detectors
and medical instrumentation.
The AMSOP-07 is operational in the full industrial temperature range of -40°C to 85°C and is available in the 8 lead SOIC
and plastic dip (PDIP) packages.

Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics
.
The
guaranteed specifications apply only for the test conditions listed.
Note 2:
Input Offset Voltage measurements are performed by automated test equipment approximately 0.5 seconds after application of power.
Note 3:
Long-Term Input Offset Voltage Stability refers to the averaged trend line of VOS vs. Time over extended periods after the first 30 days of operation.
Excluding the initial hour of operation, changes in VOS during the first 30 operating days are typically 2.5µV. Parameter is sample tested.
Note 4:
Sample tested
Note 5:
Guaranteed by design.
Note 6:
Guaranteed but not tested.
