OPA336U/2K5

Instrumentation, Op Amps, Buffer Amps Overview

The OPA336U/2K5 is a single-channel microPower CMOS operational amplifier from the MicroAmplifier series, manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.3V to 5.5V with a quiescent current of 20µA per amplifier. The device features rail-to-rail output capability, swinging within 3mV of the supply rails under a 100kΩ load. Key electrical specifications include a gain-bandwidth product of 100kHz, a slew rate of 0.03V/µs, and an input offset voltage of ±60µV typical. It utilizes an 8-pin SOIC surface-mount package.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the OPA336U support inputs exceeding the positive supply voltage?

Yes, the inputs can go beyond the power supplies without phase inversion, provided the input current is limited to 10mA or less.

What is the common-mode rejection ratio specification?

The CMRR is specified at 86dB for the OPA336U variant when the common-mode voltage is between -0.2V and (V+) - 1V.
