OPA349NA

TEXAS INSTRUMENTS  OPA349NA  运算放大器, 单路, 70 kHz, 1个放大器, 0.02 V/µs, 1.8V 至 5.5V, SOT-23, 5 引脚

The is an ultra-low power Operational Amplifier with rail-to-rail input and output. It is specifically designed for battery-powered applications. The input common-mode voltage range extends 200mV beyond the power-supply rails and the output swings to within 350mV of the rails, maintaining wide dynamic range. Unlike some MicroPower op amps, this part is unity-gain stable and require no external compensation to achieve wide bandwidth. The OPA349 features a low input bias current that allows the use of large source and feedback resistors. The OPA349 can be operated with power supplies from 1.8 to 5.5V with little change in performance, ensuring continuing superior performance even in low battery situations.
