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.

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD5516 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Storage Temperature Range . . . . . . . . . . . . – ...
