Product details

2 µV offset, 17 µA per channel — the zero-drift workhorse for precision sensor chains

Each channel draws 17 µA of supply current, which keeps the power budget lean in multi-channel battery-powered designs. The part comes in an 8-WFDFN exposed-pad package with a 2x2 mm WSON footprint, surface-mount only.

Supply range and output swing — single-rail design margin

The rail-to-rail output delivers the full supply swing into a 5 mA load per channel, which is enough to drive a typical SAR ADC input or a reference buffer without an extra gain stage. On a 3.3 V supply, the output can swing within about 10 mV of each rail at light loads, preserving the usable code range in a 12-bit or 16-bit ADC chain.

Active lifecycle — no allocation pressure on this line

For the shortage-desk buyer: this is not a part that will suddenly vanish from the franchised channel. If you are dual-sourcing for a production BOM, the OPA2333 family includes single and quad variants (OPA2333 is the dual), but no pin-compatible second source from another manufacturer is listed in the record.

Frequently asked questions

Is OPA2333PIDSGR suitable for low-power sensor applications?

Yes. With 17 µA supply current per channel, a 1.8 V minimum supply, and rail-to-rail output, the OPA2333PIDSGR is well suited for battery-powered sensor interfaces such as thermocouple amplifiers, bridge transducers, and photodiode stages where low offset and low power are both required.

Is OPA2333PIDSGR rail-to-rail output?

Yes, the output type is rail-to-rail. The input common-mode range is not rail-to-rail, so for high-side sensing near the positive rail, verify the input voltage stays within the common-mode range of the amplifier.

What is the OPA2333PIDSGR equivalent or replacement?

Within the TI Zero-Drift series, the OPA2333 is the dual-channel variant; the single-channel OPA333 and quad-channel OPA4330 are functionally similar but differ in package and channel count. For a direct replacement, stick with the OPA2333 family.
