DAC63204数据手册集成电路（IC）的数模转换器（DAC）规格书PDF

描述 Description

The 12-bit DAC63204, 10-bit DAC53204, and 8-bit DAC43204 (DACx3204) are a pin-compatible family of quad-channel, buffered, voltage-output and current-output smart digital-to-analog converters (DACs). The DAC outputs are capable of both voltage and current output. These DACx3204 support Hi-Z power-down mode and Hi-Z output during power-off condition. The DAC outputs provide a force-sense option for use as a programmable comparator and current sink. The multifunction GPIO, function generation, and NVM enable these smart DACs for processor-less applications and design reuse. These devices also have an automatically detected I2C, PMBus, or SPI interface and an internal reference.

The feature set combined with the tiny package and low power make these smart DACs an excellent choice for applications such as voltage margining and scaling, dc set-point for biasing and calibration, and waveform generation.
