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.
