ADS7804
DESCRIPTION
The ADS7804 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 ADS7804 is specified at a 100kHz sampling rate,
and guaranteed over the full temperature range. Laser-
trimmed scaling resistors provide an industry-
standard
±
10V input range, while the innovative de-
sign allows operation from a single +5V supply, with
power dissipation under 100mW.
The 28-pin ADS7804 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.
