描述 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.
