The zero-drift architecture holds input offset voltage to 20 µV maximum, eliminating the need for periodic system calibration in precision DC measurement paths such as thermocouple amplifiers, load-cell bridges, and photodiode transimpedance stages.
MSL level is typical for this class (verify with the reel label before bake decisions).
The gain bandwidth product is 900 kHz, which with the 0.4 V/µs slew rate defines the usable frequency range for precision DC and low-frequency AC signals. For audio-band or higher-speed loops, look at the OPAx188 family instead.
Yes, the amplifier type is Zero-Drift, which keeps input offset voltage at 20 µV maximum and virtually eliminates offset drift over temperature and time. This is the key feature for precision measurement without calibration.
Within the same microPOWER™ series, the OPA379AIDBVT shares the same SOT-23-5 footprint and pinout but offers a slightly higher 90 kHz GBW at 5.5 µA supply — a trade for even lower power. For higher bandwidth at similar power, the OPA333AIDBVT (350 kHz, 17 µA) is also pin-compatible. Verify the exact offset and drift specs against your error budget.
