Product details

Zero-drift precision for DC-coupled signal chains

Its 1 µV input offset voltage and 70 pA input bias current make it a fit for precision DC applications — load-cell bridges, thermocouple interfaces, and current-shunt monitors where drift over temperature would otherwise swamp the measurement.

285 µA supply current and 50 mA output drive

Quiescent current of 285 µA per channel keeps the power budget tight in multi-channel or battery-operated designs. For higher output current, consider a buffer stage.

Frequently asked questions

Is OPA335AIDR a zero-drift op-amp?

Yes, the OPA335AIDR is a zero-drift amplifier. Its auto-zero architecture keeps the input offset voltage at 1 µV typical with near-zero drift over temperature, which is the key advantage over general-purpose CMOS amplifiers.

What are the alternative or equivalent parts to OPA335AIDR?

The closest functional alternative is the TLV9351IDCKR, a general-purpose CMOS op-amp with 3.5 MHz GBW and 20 V/µs slew rate, but it has a higher typical input offset voltage of 350 µV — not a zero-drift replacement. For multi-channel designs, the OPA4374AIPWT offers four CMOS amplifiers in a single package at 6.5 MHz GBW.

Does OPA335AIDR require external compensation?

No. The OPA335AIDR is internally compensated for unity-gain stability. No external capacitor or resistor network is needed for closed-loop gains of 1 or higher.
