OPA336UJ

Instrumentation, Op Amps, Buffer Amps Overview

The OPA336UJ is a single-channel, microPower CMOS operational amplifier from the Texas Instruments MicroAmplifier series. It operates on a single supply voltage ranging from 2.3 V to 5.5 V with a typical quiescent current of 20 µA per channel. The device features rail-to-rail input and output capabilities, ensuring maximum dynamic range in low-voltage applications. Key electrical specifications include a gain-bandwidth product of 100 kHz, a slew rate of 30 mV/µs, and an input offset voltage of 500 µV. Input bias current is typically 10 pA, while input voltage noise density is 40 nV/√Hz. The component is housed in an 8-pin SOIC package and supports surface mount installation.

Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the OPA336UJ when designing circuits requiring low power consumption alongside rail-to-rail performance in a compact SOIC-8 package. Consider its 100 kHz bandwidth and 20 µA supply current for applications where power efficiency is critical but moderate speed is sufficient. Evaluate the 500 µV input offset voltage against system accuracy requirements to determine if external trimming or higher precision variants are necessary.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA336UJ belongs to the MicroAmplifier series, which focuses on single-supply, microPower CMOS operational amplifiers. This family is designed for applications demanding low cost and low power without sacrificing essential performance metrics like input/output swing.
