12-Bit 800kHz Sampling CMOS
ANALOG-to-DIGITAL CONVERTER
FEATURES
l 1.25µs THROUGHPUT TIME
l STANDARD ±2.5V INPUT RANGE
l 70dB min SINAD WITH 250kHz INPUT
l ±3/4 LSB max INL AND ±1 LSB max DNL
l INTERNAL REFERENCE
l COMPLETE WITH S/H, REF, CLOCK, ETC.
l PARALLEL DATA w/ LATCHES
l 28-PIN 0.3" PDIP AND SOIC
ADS7819
DESCRIPTION
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.
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.
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.
