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 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 appli-
cations, battery-powered instruments, and isolated sys-
tems. The DAC1220 is available in a SSOP-16
package.
