DESCRIPTION

The WM2331 is a high speed, 10-bit pipeline analogue-to-digital converter (ADC) with on-chip programmable gain amplifier (PGA) and clamp circuit, and internal voltage references. Conversion is controlled by a single clock input.

The device has a high bandwidth differential sample and hold input, which gives excellent common-mode noise immunity and low distortion. Alternatively, it can be driven in single ended fashion with an optional voltage clamp for DC restoration that can take its reference from an on-chip 10-bit DAC or an external source.
