Multiple Range, 16-/12-Bit,  
Bipolar/Unipolar, Voltage Output DACs  
Data Sheet  
AD5761/AD5721  
FEATURES  
GENERAꢀ DESCRIPTION  
8 software-programmable output ranges: 0 V to +5 V, 0 V to  
+10 V, 0 V to +16 V, 0 V to +20 V, 3 V, 5 V, 10 V, −2.5 V to  
+7.5 V; 5% overrange  
Total unadjusted error (TUE): 0.1% FSR maximum  
16-bit resolution: 2 ꢀSB maximum INꢀ  
Guaranteed monotonicity: 1 ꢀSB maximum  
Single channel, 16-/12-bit DACs  
Settling time: 7.5 μs typical  
Integrated reference buffers  
ꢀow noise: 35 nV/√Hz  
The AD5761/AD5721 are single channel, 16-/12-bit serial input,  
voltage output, digital-to-analog converters (DACs). They operate  
from single supply voltages from +4.75 V to +30 V or dual  
supply voltages from −16.5 V to 0 V VSS and +4.75 V to +16.5 V  
V
DD. The integrated output amplifier and reference buffer  
provide a very easy to use, universal solution.  
The devices offer guaranteed monotonicity, integral nonlinearity  
(INL) of 2 LSB maximum, 35 nV/√Hz noise, and 7.5 μs settling  
time on selected ranges.  
The AD5761/AD5721 use a serial interface that operates at  
clock rates of up to 50 MHz and are compatible with DSP and  
microcontroller interface standards. Double buffering allows  
the asynchronous updating of the DAC output. The input  
coding is user-selectable twos complement or straight binary.  
The asynchronous reset function resets all registers to their  
default state. The output range is user selectable, via the  
RA[2:0] bits in the control register.  
ꢀow glitch: 1 nV-sec  
1.8 V logic compatibility  
Asynchronous updating via ꢀDAC  
Asynchronous RESET to zero scale/midscale  
DSP/microcontroller-compatible serial interface  
Robust 4 kV HBM ESD rating  
Available in 16-lead TSSOP and 16-lead ꢀFCSP  
Operating temperature range: −40°C to +125°C  
The devices available in the 16-lead TSSOP and in the 16-lead  
LFCSP offer guaranteed specifications over the −40°C to +125°C  
industrial temperature range.
