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
www.DataSheet4Uco.cmomon-mode noise immunity and low distortion. The
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
