Input offset voltage is 1 µV.
Quiescent current is 285 µA.
The input bias current of 70 pA stays low enough over temperature that high-impedance sources (pH probes, pyroelectric sensors) do not see significant loading.
Yes, the amplifier type is Zero-Drift, with an input offset voltage of 1 µV and a gain bandwidth product of 2 MHz.
The TLV9351IDCKR is a pin-compatible general-purpose CMOS op-amp with higher GBW (3.5 MHz) and slew rate (20 V/µs), but it is not a zero-drift type and has a higher typical offset of 350 µV. For precision DC applications requiring the 1 µV offset, the OPA335AID remains the correct choice.
