DESCRIPTION

The 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 fullscale, 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 reduces low offset and gain errors.


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. 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 applications, battery-powered instruments, and isolated systems. The DAC1220 is available a SSOP-16 package.

NOTES: (1) Valid from AGND 20mV to AVDD 20mV, in the 16-bit mode. (2) Applies after calibration, in 16-bit mode. (3) Re-calibration can remove these errors. (4) Ideal output voltage, does not take into account gain and offset error. (5) Valid from AGND +20mV to AVDD -20mV. Outside of this range, settling time may be twice the value indicated. For 16-bit mode, = 0.22nF; for 20-bit mode, = 3.3nF.

This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.


MAXIMUM LINEARITY ERROR (LSB) ±1 PACKAGE DRAWING NUMBER 322 SPECIFICATION TEMPERATURE RANGE to +85°C


NOTE: (1) Models with a slash are available only in Tape and Reel in the quantities indicated (e.g., /2K5 indicates 2500 devices per reel). Ordering 2500 pieces of "DAC1220E/2K5" will get a single 2500-piece Tape and Reel.
