FEATURES  
DESCRIPTION  
Relative Accuracy: 1 LSB Max  
Differential Nonlinearity: 1 LSB Max  
2-mA Full-Scale Current ±20%,  
with VREF = ±10 V  
0.5 µs Settling Time  
Midscale or Zero-Scale Reset  
Separate 4Q Multiplying Reference Inputs  
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  
The DAC8802 is  
digital-to-analog converter (DAC) designed to operate  
from a single +2.7 V to 5.5 V supply.  
a dual, 14-bit, current-output  
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).  
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.
