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 V_SSand +4.75 V to +16.5 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.
