ADS7820
DESCRIPTION
The ADS7820 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 S/H,
reference, clock, interface for microprocessor use, and
three-state output drivers.
The ADS7820 is specified at a 100kHz sampling rate,
and guaranteed over the full temperature range. Laser-
trimmed scaling resistors provide a 0 to +5V input
range, with power dissipation under 100mW.
The 28-pin ADS7820 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.
