OPA2333AIDRBR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2333AIDRBR is a dual-channel, zero-drift operational amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies up to ±2.75 V. Key electrical specifications include a gain-bandwidth product of 350 kHz, a slew rate of 160 mV/µs, and an input offset voltage of 10 µV. The device draws a typical quiescent current of 17 µA per channel and provides an output current of 5 mA. It features rail-to-rail input and output capabilities, a common-mode rejection ratio of 130 dB, and low input noise density of 65 nV/√Hz. The component is housed in an 8-pin SON package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'BR' indicates the reel packaging configuration when ordering. Confirm that the A-grade variant meets your required offset voltage specifications compared to standard grades. Ensure the SON-8 footprint matches your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate the operating temperature range against your system's thermal environment requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when zero-drift performance is critical for maintaining accuracy over wide temperature variations. Compare it against other micro-power amplifiers if lower noise density is required, noting the trade-off between bandwidth and noise. Consider the SON-8 package size limitations regarding thermal dissipation and soldering capabilities. Evaluate the 17 µA quiescent current against stricter power budgets where single-channel solutions might suffice.
