16-Channel, 12-Bit Voltage-Output DAC
with 14-Bit Increment Mode
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鈥揂0. 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
鹵
2.5 V (AD5516-1),
鹵
5 V (AD5516-2),
and
鹵
10 V (AD5516-3). Access to the feedback resistor in each
channel is provided via R
