The DAC1221 is a Digital-to-Analog (D/A) converter offering 16-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 output range is two times the external reference voltage. On-chip calibration circuitry dramatically reduces offset and gain errors.

The DAC1221 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 DAC1221 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 DAC1221 is available in a SSOP-16 package.

设计工具

ADC-DAC-TO-VREF-SELECT-DESIGN-TOOL — The ADC-TO-VREF-SELECT tool enables the pairing of TI ADCs, DACs, and series voltage references.

The ADC-TO-VREF-SELECT tool enables the pairing of TI analog-to-digital converters (ADCs) and series voltage references. Users can select an ADC device and the desired reference voltage, and the tool will list up to two voltage reference recommendations.
