Texas Instruments DAC82002 16-Bit Digital-to-Analog Converter
Texas Instruments DAC82002 16-Bit Digital-to-Analog Converter (DAC) is a highly accurate, low-power, dual-channel DAC with an unbuffered voltage output. The DAC82002 works with 3.3V and 5V supplies and offers linearity of 1LSB DNL and 2LSB INL. The tiny package combined with high accuracy makes the device an excellent choice for applications such as voltage set point generation, gain and offset calibration, and power-supply control.
The Texas Instruments DAC82002 incorporates a power-on-reset circuit to ensure that the DAC output powers up at zero scale or midscale based on the status of the RSTSEL pin. It remains at that scale until a valid code is written to the device. All internal registers are asynchronously reset after the RESET pin is pulled low. The DAC82002 uses a three-wire serial peripheral interface (SPI) that is versatile and operates at clock rates of up to 50MHz.
