WM2130

WM2130 10-bit 30MSPS Analogue-To-Digital Converter Production Data, April 2001, Rev 1.2 DESCRIPTION The WM2130 is a high speed 10-bit analogue-to-digital converter and operates with independent analogue and digital supplies of 3V to 5.5V. This device includes a high bandwidth sample and hold and internal voltage references. Conversion is controlled by a single clock input. The differential-input sample and hold input gives excellent common-mode noise immunity and low distortion. The www.DataSheet4U.com device can also be driven in a single ended fashion. The device provides internal reference voltages for setting the ADC full-scale range without the requirement for external circuitry. The WM2130 can also accept external reference levels for applications where higher precision references are required. The WM2130 has also been designed to offer a speed upgrade to users of the AD876 and a replacement for the AD9200 and AD9202 devices. The WM2130 operates as an AD876 in those design slots but at speeds of up to 50% faster. FEATURES 10-bit resolution ADC 30MSPS conversion rate Wide input bandwidth (150 MHz full-power bandwidth) sample and hold input amplifier Independent analogue and digital supplies Adjustable internal voltage references Out of range indicator Low power: 87mW typical at 3V supplies Powerdown mode to 3mW typical 28-pin TSSOP package APPLICATIONS Set Top Box (STB) IF and Baseband Digitisation Medical Imaging High speed data acquisition ...
