产品概述
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. It can also be configured to handle single ended input data
converters by means of the VOCM pin (see for details). The inputs of LMP7312 can be configured in attenuation mode to
handle large input signals of up to +/- 15V, as well as in amplification mode to handle current
loops of 0-20mA and 4-20mA.The LMP7312 is equipped with a null switch to evaluate the offset of the
internal amplifier. A ensured 0.035% maximum gain error (for all gains) and a maximum gain drift of
5ppm over the extended industrial temperature range (-40° to 125°C) make the LMP7312 very
attractive for high precision systems even under harsh conditions. A low input offset voltage of
100µV and low voltage noise of 3µVpp give the LMP7312 a superior performance. The LMP7312 is fully
specified from -40° to 125°C and is available in SOIC-14 package.
