The device includes a correlated double sampling circuit, AGC, a soft clipper circuit and a low power 10-bit Analog-to-Digital Converter (ADC) together with its reference voltage regulator.
The AGC and soft clipper circuits are controlled by on-chip DACs via a serial interface.
A 10-bit DAC controls the ADC input clamp level.
