ADS7819

12-Bit 800kHz Sampling CMOS

ANALOG-to-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 1.25µs THROUGHPUT TIME

The ADS7819 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

● 70dB min SINAD WITH 250kHz INPUT

● ±3/4 LSB max INL AND ±1 LSB max DNL

● INTERNAL REFERENCE

The ADS7819 is specified at an 800kHz sampling

rate, and guaranteed over the full temperature range.

Laser-trimmed scaling resistors provide a ±2.5V input

range and inherent overvoltage protection up to ±25V.

● COMPLETE WITH S/H, REF, CLOCK, ETC.

● PARALLEL DATA w/ LATCHES

● 28-PIN 0.3" PDIP AND SOIC

The 28-pin ADS7819 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.
