ES7
True RMS-to-DC Converters
Features
•
•
True RMS-to-DC Conversion
Input level is specified up to
400mV
RMS
Description
The ES7 series are designed for the true
RMS-to-DC conversion. ES7 accept
low-level input signals from 0 to 400 mV
RMS
complex input waveforms. ES7 can be
operated form either a single supply or
dual supplies. The device draw less than 1
mA of quiescent supply current,
furthermore, an enable pin is provided to
turn-off the device, making it ideal for
battery-powered applications.
