Overview
The OPA340NA/250, produced by Texas Instruments, is a part of the OPA340 series of rail-to-rail, low-power operational amplifiers. These CMOS operational amplifiers are optimized for low-voltage, single-supply operation and are ideal for various applications including driving sampling analog-to-digital (A/D) converters, general-purpose use, and audio applications. They offer high-speed operation with a bandwidth of 5.5 MHz and a slew rate of 6 V/µs, making them suitable for dynamic and high-performance requirements. The OPA340 series operates on a single supply as low as 2.5 V and features rail-to-rail input and output, extending the input common-mode voltage range 500 mV below ground and 500 mV above the positive supply. The devices are available in single, dual, and quad versions, providing design flexibility.
