OPA349NA/250 Description

Short technical summary and product information.

The Texas Instruments OPA349NA/250 is a single-channel, low quiescent current operational amplifier designed for a wide range of applications. It operates from a supply voltage range of 1.8V to 5.5V, making it suitable for various power-sensitive designs.

 

Key electrical characteristics include a gain-bandwidth product of 70kHz and a slew rate of 0.02V/µs. The amplifier boasts a low quiescent current of just 1µA per channel and a low input bias current of 10pA maximum. It also features Rail-to-Rail input and output capabilities, allowing for maximum dynamic range.

 

The OPA349NA/250 has an offset voltage of 10mV maximum at 25°C and an offset drift of 15µV/°C typical. The common-mode rejection ratio is 60dB typical, and the output current is 8mA typical.

 

This operational amplifier is available in a compact SOT-23-5 surface-mount package, making it ideal for space-constrained applications. The operating temperature range is -40°C to 85°C.
