Description
The ICL7112 is a monolithic 12-bit resolution, fast
successive approximation A/D converter. It uses thin film
resistors and CMOS circuitry combined with an on-chip
PROM calibration table to achieve 12-bit linearity without
laser trimming. Special design techniques used in the DAC
and comparator result in high speed operation, while the
fully static silicon-gate CMOS circuitry keeps the power
dissipation very low.
Microprocessor bus interfacing is eased by the use of
standard memory WRite and ReaD cycle timing and control
signals, combined with Chip Select and Address pins. The
digital output pins are byte-organized and three-state gated
for bus interface to 8-bit and 16-bit systems.
The lCL7112 provides separate Analog and Digital grounds
for increased system accuracy. Operating with
±
5V supplies,
the lCL7112 accepts 0V to +10V input with a -10V reference
or 0V to -10V input with a +10V reference.
