DESCRIPTION
The ADS7804 is a complete 12-bit sampling analog-to-digital
(A/D) converter using state-of-the-art CMOS structures. It
contains a complete 12-bit, capacitor-based, SAR A/D converter
with S/H, reference, clock, interface for microprocessor
use, and three-state output drivers.
The ADS7804 is specified at a 100kHz sampling rate, and
guaranteed over the full temperature range. Laser-trimmed
scaling resistors provide an industrystandard
±10V input range, while the innovative design
allows operation from a single +5V supply, with power
dissipation under 100mW.
The 28-pin ADS7804 is available in plastic 0.3" DIP and SO
packages, both fully specified for operation over the industrial
–40°C to +85°C range.
