ICL7121 - 16-Bit Multiplying Microprocessor-Compatible D/A Converter

General Description

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.

Key Features

  • 16-Bit Resolution.
  • Low Integral Linearity Error -0.003% FSR.
  • Monotonic to 16 Bits Over Full Military Temperature Range (LM Grade).
  • Microprocessor Compatible with Buffered Inputs.
  • Bipolar.

® October 1997 M ECO R T NO DED ME N FO R DES NEW S IG N ICL7121 16-Bit Multiplying Microprocessor-Compatible D/A Converter Description 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.
