12-Bit 600kHz Sampling CMOS

ANALOG-to-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 600kHz THROUGHPUT RATE

The ADS7831 is a complete 12-bit sampling A/D

using state-of-the-art CMOS structures. It contains a

complete 12-bit capacitor-based SAR A/D with inher-

ent S/H, reference, clock, interface for microprocessor

use, and three-state output drivers.

● STANDARD ±2.5V INPUT RANGE

● 69dB min SINAD WITH 250kHz INPUT

● COMPLETE WITH S/H, REF, CLOCK, ETC.

● PARALLEL DATA w/LATCHES

● FULLY SPECIFIED –40°C TO +85°C

● 15MHz –3dB BANDWIDTH

The ADS7831 is specified at a 600kHz sampling rate,

and guaranteed over the full temperature range. A

±2.5V input range and excellent Nyquist performance

provide an optimum solution in ±5V supply systems.

● 28-PIN 0.3" PDIP AND SOIC

The 28-pin ADS7831 is available in a plastic 0.3" DIP

and in an SOIC, both fully specified for operation over

the industrial –40°C to +85°C range.
