Product details

Zero-drift precision for DC-coupled signal chains

The Texas Instruments OPA335AIDR is a single-channel zero-drift amplifier in an 8-SOIC package. 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. Rail-to-rail output swings to within millivolts of the 2.7 V to 5.5 V supply rails, so it can drive an ADC input directly without a second gain stage.

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. The 50 mA output current rating is enough to drive a reference input, a small relay coil, or a headphone line — but not a power stage. 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.
