Quiescent current is 790 µA per amplifier — reasonable for a precision part, though not micropower. The 35 mA output current per channel can drive moderate loads like a 2 kΩ feedback network or a 100 Ω headphone, but not a relay coil or motor.","metaTitle":"TI OPA277UA precision op-amp, 1 MHz, 20 µV offset, 8-SOIC","metaDescription":"Texas Instruments OPA277UA general-purpose precision op-amp: 1 MHz GBW, 20 µV offset, 0.8 V/µs slew rate, 790 µA supply, -40°C to 85°C, 8-SOIC.
