DAC63004中文资料具有 I2C、SPI、PWM 的超低功耗 4 通道 12 位智能 DAC数据手册TI规格书

描述 Description

The 12-bit DAC63004 and 10-bit DAC53004 (DACx3004) are a pin-compatible family of ultra-low-power, 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 DACx3004 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 ultra-low-power make these smart DACs an excellent choice for applications such as land mobile radio, pulseoximeter, notebook PCs, and other battery-operated applications for biasing, calibration, and waveform generation.
