The 12-bit DAC63202 and 10-bit DAC53202 ( DACx3202) are a pin-compatible family of dual-channel, buffered, voltage-output and current-output smart digital-to-analog converters (DACs). The DACx3202 devices support Hi-Z power-down mode and Hi-Z output during power-off conditions. 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 automatically detect I2C, PMBus, and SPI interfaces and contain 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.

Updated release of the DAC63204EVM-GUI. Version 1.1.0 now has I2C and SPI capability.
First release of the DACX3x0X-SINEWAVE-CALC. The Calculator sheet takes certain input parameters from the user like the DAC device, reference setting, the supply given to the DAC (VDD), and the sine wave frequency. The Pseudocode sheet takes generates the register settings for configuring the device in sine wave mode based on the settings chosen in the Calculator sheet.
DACx3x0x family power-consumption calculator tool
First release of the DACx3x0x-PWM-CALC. The Calculator sheet takes certain input parameters from the user like the DAC output mode, number of active/powered-on channels, current output range, reference setting, the supply given to the DAC (VDD), and the load resistance for each channel. The Average Power sheet takes certain input parameters from the user like the DAC output mode, VDD(V), duty cycle(%), total typical static current and total max static current. Users can have any number of DAC configurations as long as the duty cycle adds up to 100%. The total typical static current and total max static current for each DAC configuration can be calculated on the Calculator sheet by setting DAC output mode, number of active/powered-on channels, current output range, reference setting, the supply given to the DAC (VDD), and the load resistance for each channel for each DAC configuration.
