The WM2331 is a high speed, 10-bit pipeline analogue-todigital 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. The WM2331 provides internal reference voltages for setting the ADC full-scale range without the requirement for external circuitry. However, it can also accept external references for applications where common or high-precision references are required.
