DESCRIPTION
The ADS7810 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 ADS7810 is specified at an 800kHz sampling
rate, and guaranteed over the full temperature range.
Laser-trimmed scaling resistors provide the industry-
standard 10V input range, while an innovative design
allows operation from 5V supplies.
The 28-pin ADS7810 is available in a plastic SOIC
fully specified for operation over the industrial –40 C
to +85 C range.
