12-Bit 800kHz Sampling CMOS
ANALOG-to-DIGITAL CONVERTER
FEATURES
l 1.25µs THROUGHPUT TIME
l STANDARD ±10V INPUT RANGE
l 69dB 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 SOIC
ADS7810
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.
