GENERAL DESCRIPTION
The AD5516 is a 16-channel, 12-bit voltage-output DAC. The selected DAC register is written to via the 3-wire serial interface. DAC selection is accomplished via address bits A3–A0. 14-bit resolution can be achieved by fine adjustment in Increment/ Decrement Mode (Mode 2). The serial interface operates at clock rates up to 20 MHz and is compatible with standard SPI, MICROWIRE, and DSP interface standards.
