ICL7134 Datasheet 14-bit Multiplying Microprocessor-compatible D/a Converter

Manufacturer: Intersil (now Renesas)

Overview: ® December 1997 NO CO T RE N MME FO DED RN E N ESIG WD S ICL7134 14-Bit Multiplying Microprocessor-Compatible D/A.

General Description

The ICL7134 combines a four-quadrant multiplying DAC using thin film resistor and CMOS circuitry with an on-chip PROM-controlled correction circuit to achieve true 14-bit linearity without laser trimming.

Microprocessor bus interfacing is eased using standard memory WRITE cycle timing and control signal use.

Two input buffer registers are separately loaded with the 8 least significant bits (LS register) and the 6 most significant bits (MS register).

Key Features

  • 14-Bit Linearity (0.003% FSR).
  • No Gain Adjustment Necessary.
  • Microprocessor-Compatible with Double Buffered Inputs.
  • Bipolar.
