Dual 1.8 V micropower zero-drift op amp, rail-to-rail I/O — SOIC-8
The OPA2333AIDR is a dual CMOS zero-drift operational amplifier from Texas Instruments. It combines microvolt-level offset and near-zero drift with only 17 µA quiescent current per amplifier, which makes it a common choice for battery-powered sensor front ends, bridge and thermocouple amplifiers, medical instrumentation and precision current sensing. It runs from a single 1.8 V to 5.5 V supply with rail-to-rail input and output, and is specified from –40 °C to 125 °C.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Is the OPA2333AIDR still in production?
Yes. Texas Instruments lists the OPA2333 as Active. Lead times have been extended, so we recommend confirming quantity and date codes before committing to a build schedule.
What should I check when sourcing an alternative package or grade?
The OPA2333 also comes in a DFN (DRB) package and other suffixes; these are not drop-in for the SOIC-8 footprint. For a different part, compare offset, drift, quiescent current and rail-to-rail input range against your design margins before substituting.
