OPA277U IC OPAMP GP 1 CIRCUIT 8SOIC

The OPAx277 series of precision operational amplifiers replace the industry standard OP-177. The
OPAx277 devices offer improved noise, wider output voltage swing, and are twice as fast with half the
quiescent current. Features include ultra-low offset
voltage and drift, low bias current, high commonmode rejection, and high power supply rejection.
The OPAx277 operate from ±2-V to ±18-V supplies with excellent performance. Unlike most op amps that
are specified at only one supply voltage, the OPAx277 series is specified for real-world applications; a single
limit applies over the ±5-V (10-V) to ±15-V (30-V) supply range. High performance is maintained as the
amplifiers swing to the specified limits. Because the initial offset voltage (±20 μV, maximum) is so low,
user adjustment is usually not required. However, the single version (OPA277) provides external trim pins
for special applications.
