The OP07D is a precision, ultralow offset amplifier. It integrates
low power (1.1 mA typical), low input bias current (±1 nA
maximum), and high CMRR/PSRR (130 dB) in the small DIP
package. Operation is fully specified from ±5 V to ±15 V supply.

The OP07D provides higher accuracy than industry-standard
OP07-type amplifiers due to Analog Devices’ iPolar™ process,
which supports enhanced performance in a smaller footprint.
These performance enhancements include wider output swing,
lower power, and higher CMRR (common-mode rejection
ratio) and PSRR (power supply rejection ratio). The OP07D
maintains stability of offsets and gain virtually regardless of
variations in time or temperature. Excellent linearity and gain
accuracy can be maintained at high closed-loop gains.

The OP07D is fully specified over the extended industrial tem­perature range of −40°C to +125°C. The OP07D amplifier is
available in 8-lead DIP and the popular 8-lead, narrow SOIC
lead-free packages.

may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
