20-Bit Low Power  
DIGITAL-TO-ANALOG CONVERTER  
FEATURES  
APPLICATIONS  
● 20-BIT MONOTONICITY GUARANTEED  
● PROCESS CONTROL  
OVER –40°C to +85°C  
● ATE PIN ELECTRONICS  
● CLOSED-LOOP SERVO-CONTROL  
● SMART TRANSMITTERS  
● PORTABLE INSTRUMENTS  
● LOW POWER: 2.5mW  
● VOLTAGE OUTPUT  
● SETTLING TIME: 2ms to 0.012%  
● MAX LINEARITY ERROR: ±0.0015%  
● ON-CHIP CALIBRATION  
The DAC1220 features a synchronous serial interface.  
In single-converter applications, the serial interface  
can be accomplished with just two wires, allowing  
low-cost isolation. For multiple converters, a CS signal  
allows for selection of the appropriate D/A converter.  
DESCRIPTION  
The DAC1220 is a 20-bit digital-to-analog (D/A)  
converter offering 20-bit monotonic performance over  
the specified temperature range. It utilizes delta-sigma  
technology to achieve inherently linear performance  
in a small package at very-low power. The resolution  
of the device can be programmed to 20 bits for full-  
scale, settling to 0.003% within 15ms typical, or 16  
bits for full-scale, settling to 0.012% within 2ms max.  
The output range is two times the external reference  
voltage. On-chip calibration circuitry dramatically re-  
duces low offset and gain errors.  
The DAC1220 has been designed for closed-loop  
control applications in the industrial process control  
market and high-resolution applications in the test and  
measurement market. It is also ideal for remote appli-  
cations, battery-powered instruments, and isolated sys-  
tems. The DAC1220 is available in a SSOP-16  
package.
