简 介:WM2331 10-bit 30MSPS ADC with PGA and Clamp
Production Data, April 2001, Rev 1.4
DESCRIPTION
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. A bidirectional 10-bit parallel interface is used both to control the device and to read ADC conversion data. ADC data can be output in unsigned binary or two’s complement format. An out-of-range output pin indicates when the input signal is outside the converter’s range. The WM2331 operates with independent analogue and digital supplies of 3V to 5.5V and is supplied in a 28-pin TSSOP package.
