Product Overview
The OPA177 is a Texas Instruments precision bipolar operational amplifier for Signal_Chain designs that require low input offset, controlled drift, high gain, and defined bias-current behavior. The feature summary lists 25 µV maximum low offset voltage, 0.3 µV/°C maximum offset-voltage drift, 134 dB minimum open-loop gain, ±2 nA maximum input bias current, and 1.3 mA typical quiescent current.
The device supports a 6 V to 36 V supply range. Recommended operating conditions specify 6 V minimum, 30 V nominal, and 36 V maximum for single-supply use, or ±3 V minimum, ±15 V nominal, and ±18 V maximum for dual-supply use. The recommended ambient operating temperature range is -40 °C to 85 °C.
Package options include D SOIC-8 at 4.9 mm × 6 mm and P PDIP-8 at 9.81 mm × 9.43 mm. The pinout provides offset trim on pins 1 and 8, inverting and noninverting inputs on pins 2 and 3, supplies on pins 4 and 7, output on pin 6, and a no-internal-connection pin 5 that can be left floating.
