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 RFB0 to RFB15 pins.
The device is operated with AVCC = 5 V ± 5%, DVCC = 2.7 V to
5.25 V, VSS = –4.75 V to –12 V, and VDD = +4.75 V to +12 V
and requires a stable 3 V reference on REF_IN.
