Product Overview
The OPA2330 is a Texas Instruments dual zero-drift CMOS operational amplifier in the Signal_Chain category. The dual version provides two amplifier channels and uses rail-to-rail input and output operation. Its feature specifications include 50 µV maximum input offset voltage, 0.25 µV/°C maximum offset voltage drift, 1.1 µVPP low-frequency noise from 0.1 Hz to 10 Hz, and 35 µA maximum quiescent current.
Supply operation covers 1.8 V to 5.5 V for single-supply systems and ±0.9 V to ±2.75 V for dual-supply systems. Recommended supply limits are 1.8 V minimum, 5 V nominal, and 5.5 V maximum for single-supply operation, or ±0.9 V minimum, ±2.5 V nominal, and ±2.75 V maximum for dual-supply operation. The device is specified from -40°C to 125°C.
OPA2330 package options include SOIC-8 at 4.90 mm x 3.91 mm, VSSOP-8 at 3.00 mm x 3.00 mm, and SON-8 at 3.00 mm x 3.00 mm. The SOIC, VSSOP, and SON packages use 8 pins; the SON thermal die pad is connected to V-. Internal EMI filtering supports use in precision analog signal paths.

Procurement Notes
When requesting a quote for OPA2330, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
