Technical details

Precision dual op-amp for low-drift signal chains

Rail-to-rail output and a 20 V/µs slew rate let it handle fast transients in precision DC and low-frequency AC paths. Supply span from 4.5 V to 36 V covers common industrial and automotive rails without a secondary regulator. The 8-VSSOP package fits tight mixed-signal boards where two channels need matched drift performance.

1.5 µV offset — the precision floor for sensor front-ends

A 1.5 µV typical input offset voltage and 70 pA input bias current keep error low with high source impedances.

14 MHz GBW at 1.3 mA per channel — bandwidth without a power penalty

The 14 MHz gain-bandwidth product and 1.3 mA supply current per channel suit multi-channel data-acquisition boards with tight per-channel power budgets.

Rated for -40°C to 125°C ambient, the OPA2189IDGKT accepts a 4.5 V to 36 V supply span. Surface-mount 8-VSSOP package fits compact PCBs.

No direct second-source alternate is listed in the TI documentation, but the TLV9362IDDFR (10.6 MHz, 400 µV offset) is a general-purpose dual that shares the same 4.5 V to 36 V supply range and -40°C to 125°C temperature grade, though its higher offset and lower bandwidth make it a functional alternative only where the 1.5 µV precision floor is not critical.
