A Flexible 4-Channel Analog Front End for Wide Dynamic Range Signal Conditioning

September 05, 2012 // By Analog Devices
The circuit shown in Figure 1 is a flexible signal conditioning circuit for processing signals of wide dynamic range, varying from several mV p-p to 20 V p-p. The circuit provides the necessary conditioning and level shifting and achieves the dynamic range using the internal programmable gain amplifier (PGA) of the high resolution analog-to-digital converter (ADC).
