DESCRIPTIONThe DAC8832 is a single, 16-bit, serial-inputvoltage-output digital-to-analogca converter (DACoperating from a single 3 V to 5 V power supply. TheDAC8832 provides excellent linearity (1 LSB INL)low glitch, low noise, and fast settling (1.0 uS to 1/2LSB of full-scale output) over the specifiedtemperature range of -40C to +85°C. The output isunbuffered,which reduces the power consumptionand the error introduced by the buffer.
This device features a standard high-speed (clock upto 50MMHz). 3 or 5 SPl serial interface tocommunicate with a DSP or microprocessor.
The DAC8832 provides unipolar or bipolar output+VReF) when working with an external buffer, and isreset to mid-code after power-up. for optimumperformance. a set of Kelvin connections to theexternal reference and the exact ground input areprovided.
The DAC8832 is available in a QFN-14 package, andis pin-to-pin compatible with the DAC8831IRGYwhich is reset to zero code after power-up.
