DESCRIPTION
The ADS7831 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 ADS7831 is specified at a 600kHz sampling rate,
and guaranteed over the full temperature range. A
provide an optimum solution in 5V supply systems.
The 28-pin ADS7831 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.
2.5V input range and excellent Nyquist performance
