Product details

Single general-purpose op-amp for industrial signal chains

With a supply span from 2.7 V to 36 V, it supports both single-supply and split-rail configurations.

Supply range and quiescent current — sizing the rail

The 200 µA quiescent current is low enough for loop-powered 4-20 mA transmitters and battery-backed instrumentation. At 8 mA output drive per channel, it can directly feed a microcontroller ADC input or drive a modest load.

For dual-sourcing or higher-speed requirements, the TLV9351IDCKR (3.5 MHz, rail-to-rail output) is a functional alternative worth evaluating — it shares the same single-channel general-purpose role but offers wider bandwidth and lower input bias current.

Frequently asked questions

Is OPA237UA active or obsolete?

No discontinuation notice or last-time-buy has been issued. It is ROHS3 compliant.

Is OPA237UA single or dual op amp?

The OPA237UA is a single-channel (one circuit) operational amplifier.

What is the OPA237UA equivalent or replacement?

For a higher-bandwidth alternative, the TLV9351IDCKR (3.5 MHz, rail-to-rail output, 10 pA input bias) is a functional peer in the same single-channel general-purpose class. Evaluate the parametric differences — particularly supply range and output swing — before substituting.
