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 inter-
face. DAC selection is accomplished via address bits A3–A0.
14-bit resolution can be achieved by fine adjustment in Incre-
ment/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 the R_FB0 to R_FB15 pins.
The device is operated with AV_CC = 5 V ± 5%, DV_CC = 2.7 V
to 5.25 V, V_SS = –4.75 V to –12 V, and V_DD = +4.75 V to +12 V,
and requires a stable 3 V reference on REF_IN.
