## Description

The OPA743NA is a single-channel CMOS operational amplifier from Texas Instruments featuring rail-to-rail input and output capability. It operates over a supply voltage range of 3.5V to 12V and delivers a typical gain bandwidth product of 7MHz with a slew rate of 10V/µs. The amplifier consumes only 1.1mA typical quiescent current per channel, making it suitable for low-power applications.

Key electrical characteristics include a maximum input offset voltage of 7mV at 25°C, typical offset drift of 8µV/°C, and a maximum input bias current of 10pA. The common-mode rejection ratio is 84dB typical, and the output can swing within 75mV of the supply rails. The input common-mode range extends 100mV beyond the negative supply.

The OPA743NA is available in two package options: a 5-pin SOT-23 and an 8-pin SOIC, accommodating different PCB layout needs. It is designed for general-purpose signal conditioning, sensor interfaces, and battery-powered equipment where low power and rail-to-rail operation are critical.
