Interface This device features a standard high-speed (clock up
to 50MHz), 3 V or 5 V SPI serial interface to
communicate with a DSP or microprocessor.
The DAC8832 provides unipolar or bipolar output
(В±VREF) when working with an external buffer, and is
reset to mid-code after power-up. For optimum
performance, a set of Kelvin connections to the
external reference and the analog ground input are
provided. APPLICATIONS The DAC8832 is a single, 16-bit, serial-input,
voltage-output digital-to-analog converter (DAC)
operating from a single 3 V to 5 V power supply. The …
