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. The output volt-

age range is fixed at ± 2.5 V (AD5516-1), ± 5 V (AD5516-2),

and ± 10 V (AD5516-3). Access to the feedback resistor in each

channel is provided via R

The device is operated with AV

5.25 V, V

and requires a stable 3 V reference on REF_IN.
