ICL7121 Description
The ICL7121 achieves 0.003% linearity without laser trimming by bining a four quadrant multiplying DAC using thin film resistors with an on-chip PROM-controlled correction circuit. Silicon-gate CMOS circuitry keeps the power dissipation very low. Microprocessor bus interfacing is eased using standard memory WRITE cycle timing and control.
