AD5516
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 volt­age 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
= –4.75 V to –12 V, and V
SS
and requires a stable 3 V reference on REF_IN.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

CAUTION

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.
