16-bit Multiplying Microprocessor-compatible D/a Converter

16-bit Multiplying Microprocessor-compatible D/A Converter Corporation,The ICL7121 achieves 0.003% linearity without laser trimming by combining 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. The input Buffer Register is loaded with the 16-bit input and directly controls the output switches. The Register is transparent if WR and CS are held low. The ICL7121 is designed and programmed for bipolar operation. There is an offset resistor to the output which should be connected to -VREF and an inverter on the MSB line, giving the DAC a 2s complement bipolar transfer function. Two extra resistors are included on the chip to facilitate the reference inversion, so that only an external op- amp is needed. By Intersil Corporation
