ADC08B200

8-Bit, 200 MSPS A/D Converter with Capture Buffer

General Description

Features

The ADC08B200 is a high speed analog-to-digital converter

(ADC) with an integrated capture buffer. The 8-bit, 200 MSPS

A/D core is based upon the proven ADC08200 with integrated

track-and-hold and is optimized for low power consumption.

This device contains a selectable size capture buffer of up to

1,024 bytes that allows fast capture of an input signal with a

slower readout rate. An on-chip clock PLL circuit provides the

option of on-chip clock rate multiplication to provide the high

speed sampling clock.

Power-down feature

■

The ADC08B200 is resistant to latch-up and the outputs are

short-circuit proof. The top and bottom of the ADC08B200's

reference ladder are available for connections, enabling a

wide range of input possibilities. The digital outputs are TTL/

CMOS compatible with a separate output power supply pin to

support interfacing with 2.7V to 3.3V logic. The digital inputs

and outputs are low voltage TTL/CMOS compatible and the

output data format is straight binary.
