Overview
The OPA2340UA/2K5 is a dual single-supply, rail-to-rail, low-power operational amplifier produced by Texas Instruments. This device is part of the OPA340 series, which is optimized for low-voltage, single-supply operation. The OPA2340UA/2K5 is particularly suited for applications requiring high-speed operation, low power consumption, and minimal crosstalk between channels.
The amplifier features rail-to-rail input and output, making it ideal for driving sampling analog-to-digital (A/D) converters, general-purpose applications, and audio systems. It also provides I/V conversion at the output of digital-to-analog (D/A) converters. The device operates on a single supply as low as 2.5 V and is available in various package options, including the 8-pin SOIC surface mount package.
