A data acquisition system includes a programmable gain amplifier, an analog-to-digital converter, a filter, and control circuitry. The programmable gain amplifier is operatively connected to receive an analog input signal on its input and generates an amplified signal on its output in accordance with gain control signals. The analog-to-digital converter is operatively connected to receive the amplified signal from the amplifier and generates a digitized signal on its output. The filter is operatively connected to receive the digitized signal from the converter and generates a filtered digital signal on its output. The control circuitry is operatively connected to the amplifier and to the converter and is also responsive to the gain control signals for dynamically adjusting power between the amplifier and converter when the gain control signals are changed.
