Product Introduction

Overview

The OPA2348AIDCNTG4 is a dual-channel, low-power, CMOS operational amplifier produced by Texas Instruments. It is part of the OPAx348 series, which includes single, dual, and quad-channel variants. This amplifier is designed for low-power applications and features a wide bandwidth of 1 MHz and a low quiescent current of 45 µA. The OPA2348AIDCNTG4 is suitable for single-supply operations ranging from 2.1 V to 5.5 V, making it versatile for various battery-powered and portable devices. Its rail-to-rail input and output capabilities enhance the dynamic range, and the extended temperature range of –40°C to +125°C adds design flexibility.
