ICL7112

12-Bit, High-Speed,

January 1998

CMOS µP-Compatible A/D Converter

Features

Description

• 12-Bit Resolution and Accuracy

• No Missing Codes

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 Compatible Byte-Organized Buffered

Outputs

• Auto-Zeroed Comparator for Low Offset Voltage

• Low Linearity and Gain Errors

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.

• Low Power Consumption (60mW)

• No Gain or Offset Adjustment Necessary

• Provides 3% Usable Overrange

• Fast Conversion (40µs)

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.
