ICL7121

16-Bit Multiplying

October 1997

Microprocessor-Compatible D/A Converter

Features

Description

• 16-Bit Resolution

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.

• Low Integral Linearity Error -0.003% FSR

• Monotonic to 16 Bits Over Full Military Temperature

Range (LM Grade)

Microprocessor bus interfacing is eased using standard

memory WRITE cycle timing and control. The input buffer

the output switches. The register is transparent if WR and

CS are held low.

• Microprocessor Compatible with Buffered Inputs

• Bipolar Application Requires No External Resistors

• Output Current Settling Time 3µs Max (1µs Typ)

• Low Linerarity and Gain Temperature Coefficients

• Low Power Dissipation (25mW)

The ICL7121 is designed and programmed for bipolar

operation. There is an offset resistor to the output which

should be connected to -V

and an inverter on the MSB

REF

• Full Four-Quadrant Multiplication

line, giving the DAC a 2’s 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.

• Low Differential Nonlinearity Error at Bipolor Zero
