Overview
The OPA340NA/3K is a single-supply, rail-to-rail CMOS operational amplifier produced by Texas Instruments. It is part of the OPA340 series, which is optimized for low-voltage, single-supply operation. This amplifier is ideal for various applications, including driving sampling analog-to-digital (A/D) converters, general-purpose use, and audio applications. It also provides I/V conversion at the output of digital-to-analog (D/A) converters. The OPA340NA/3K is available in a compact 5-pin SOT-23 (DBV) package, making it suitable for space-constrained designs.
