Low Noise AC Amplifier with Programmable Gain and Bandwidth

Jan 20th 2000
Two LTC6910 programmable gain amplifiers can be combined to provide independent gain and bandwidth control using two 3 bit digital words. The Gain Control PGA simply varies the circuit gain from 1 to 100. The Bandwidth Control PGA puts signal gain inside the feedback loop of the amplifier. As this gain is increased the effective ...

Autoranging True RMS-to-DC Converter

Sep 10th 1999
A programmable gain amplifier (LTC6910-2) and a window comparator (LTC6700-1) and some control logic creates a wide dynamic range RMS to DC converter. The comparator monitors the DC output and signals whether to increment or decrement the gain to maintain a predetermined output voltage range. Knowing the output DC voltage ...
