LMP7312 Description
The LMP7312 is a digitally programmable variable gain amplifier/attenuator. Its wide input voltage range and superior precision make it a prime choice for applications requiring high accuracy such as data acquisition systems for IO modules in programmable logic control (PLC). The LMP7312 provides a differential output to maximize dynamic range and signal to noise ratio, thereby reducing the overall system error.
