High Integration: 16-channel DAC in 12x12 m m 2 LFBGA
Guaranteed Monotonic
T he AD5517 is a 16-channel voltage-output 14-bit DAC. T he
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 is achieved by fine adjusment in Mode 2. T he
serial interface operates at clock rates up to 20 MHz and is
compatible with standard SPI, MICROWIRE and DSP inter-
face standards. T he output voltage range is fixed at ±2.5 V
(AD5517-1), ±5 V (AD5517-2) and ±10 V (AD5517-3). Ac-
cess to the feedback resistor in each channel is provided via
Low Pow er, SPITM, MICROWIRETM and DSP-Com patible
3-Wire Serial Interface
Output Im pedance 0.5Ω
Output Voltage Range
± 2.5 V (AD5517-1)
± 5 V (AD5517-2)
± 10V (AD5517-3)
Asynchronous RESET facility
Daisy-Chaining Option
RFB0 to RBF15 pins.
T he 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 2.5 V reference on REF_IN.
Tem perature Range -40oC to +85oC
