Input bias current is 30 pA typical, low enough that a 10 kΩ source resistor contributes only 0.3 µV of offset error — negligible for most precision circuits, though a photodiode or high-impedance sensor front-end may still benefit from guarding the input traces on the PCB. ## Supply current, output drive, and temperature range Quiescent supply current is 1.9 mA per amplifier — this is the standing power draw before any load; at 5 V supply that is 9.5 mW, reasonable for a precision amplifier in a multi-channel system where several devices share a rail. Output can source or sink 60 mA, enough to drive an ADC reference input, a small relay coil through a series resistor, or a 50 Ω transmission line terminated at the far end — but the thermal limit of the 8-SOIC package at 125°C ambient will restrict continuous output current to well below that figure. ## Sourcing and supply posture Texas Instruments lists the OPA388IDR as an active product with no announced discontinuation — it is available through authorized distribution and independent channels.","metaTitle":"Texas Instruments OPA388IDR Zero-Drift Op-Amp, 10 MHz","metaDescription":"TI OPA388IDR zero-drift op-amp: 0.25 µV offset, 10 MHz GBW, 5 V/µs slew rate, rail-to-rail output, 8-SOIC.
