OPA333AIDBVT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA333AIDBVT is a single-channel, zero-drift operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 350 kHz and a slew rate of 160 mV/µs. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V, or dual supplies of ±0.9 V to ±2.75 V. Key electrical specifications include an input offset voltage of 2 µV, a quiescent current of 17 µA, and an input bias current of 70 pA. It utilizes an SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'VT' indicates tape-and-reel packaging when sourcing components. Confirm that the operating environment remains within the specified -40°C to +125°C junction temperature range to ensure performance integrity. Cross-reference the manufacturer datasheet for any updates regarding RoHS compliance status or recommended soldering profiles for the SOT-23-5 package.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications prioritizing DC accuracy and low power consumption over high-speed bandwidth. The zero-drift technology makes it suitable for slow-moving signals where offset errors must be minimized without external calibration. Ensure the system design accommodates the rail-to-rail input/output limitations near the supply rails if full-scale signal handling is required.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA333 family of micropower CMOS operational amplifiers. It shares architectural similarities with other zero-drift devices but is optimized for single-supply operation in compact packages. The OPA333 series is designed to replace traditional bipolar or JFET input amplifiers in low-power precision applications, offering superior thermal stability and lower noise than standard CMOS alternatives.
