DAC8814  
SBAS338D–JANUARY 2005–REVISED SEPTEMBER 2006  
Quad, Serial Input 16-Bit Multiplying Digital-to-Analog Converter  
FEATURES  
DESCRIPTION  
•
•
•
Relative Accuracy: 1 LSB Max  
Differential Nonlinearity: 1 LSB Max  
2-mA Full-Scale Current  
with VREF = ±10 V  
0.5-µs Settling Time  
Midscale or Zero-Scale Reset  
Four Separate 4Q Multiplying Reference  
Inputs  
The DAC8814 is a quad, 16-bit, current-output  
digital-to-analog converter (DAC) designed to  
operate from a single +2.7-V to 5.0-V supply.  
The applied external reference input voltage VREF  
determines the full-scale output current. An internal  
•
•
•
feedback resistor (RFB  
)
provides temperature  
tracking for the full-scale output when combined with  
an external I-to-V precision amplifier.  
A doubled buffered serial data interface offers  
high-speed, 3-wire, SPI and microcontroller  
compatible inputs using serial data in (SDI), clock  
(CLK), and a chip-select (CS). In addition, a serial  
data out pin (SDO) allows for daisy-chaining when  
•

Reference Bandwidth: 10 MHz  
Reference Dynamics: –105 dB THD  
SPI™-Compatible 3-Wire Interface:  
50 MHz  
Double Buffered Registers Enable  
Simultaneous Multichannel Change  
Internal Power-On Reset  
•
•
•
•
multiple  
packages  
are  
used.  
A
common  
level-sensitive load DAC strobe (LDAC) input allows  
simultaneous update of all DAC outputs from  
previously loaded input registers. Additionally, an  
internal power-on reset forces the output voltage to  
zero at system turn on. An MSB pin allows system  
reset assertion (RS) to force all registers to zero  
code when MSB = 0, or to half-scale code when  
MSB = 1.
