Product Overview
The OPA4277 is a Texas Instruments high-precision quad operational amplifier in the Signal_Chain category. The quad version provides four amplifier channels and is specified with 10 µV input offset voltage, ±20 µV maximum initial offset voltage, and ±0.1 µV/°C offset voltage drift. Its precision parameters also include 134 dB open-loop gain, 140 dB common-mode rejection, and 130 dB power-supply rejection.
For supply design, the device supports dual-supply operation from ±2 V to ±18 V. Recommended operating conditions list single-supply operation from 4 V minimum to 36 V maximum, with 30 V nominal, and dual-supply operation from ±2 V minimum to ±18 V maximum, with ±15 V nominal. Quiescent current is specified as 800 µA per amplifier.
The OPA4277 is available in 14-pin SOIC (D), 3.91 mm × 8.65 mm, and 14-pin PDIP (P), 6.35 mm × 19.30 mm packages. It is unity-gain stable, free from phase inversion, and has noise characterized over a 0.1 Hz to 10 Hz measurement bandwidth.
