GENERAL DESCRIPTION
The AD5541/AD5542 are single, 16-bit, serial input, voltage
output digital-to-analog converters (DACs) that operate from
a single 2.7 V to 5.5 V supply. The DAC output range extends
from 0 V to V
REF
.
The DAC output range extends from 0 V to V
REF
and is guaranteed
monotonic, providing 1 LSB INL accuracy at 16 bits without
adjustment over the full specified temperature range of −40°C to
+85°C. Offering unbuffered outputs, the AD5541/AD5542
achieve a 1 µs settling time with low power consumption and low
offset errors. Providing a low noise performance of 11.8 nV/√Hz
and low glitch, the AD5541/AD5542 is suitable for deployment
across multiple end systems.
The AD5542 can be operated in bipolar mode, which generates
a ±V
REF
output swing. The AD5542 also includes Kelvin sense
connections for the reference and analog ground pins to reduce
layout sensitivity.
The AD5541/AD5542 utilize a versatile 3-wire interface that is
compatible with SPI, QSPI™, MICROWIRE™ and DSP interface
standards. The AD5541/AD5542 are available in 8-lead and
14-lead SOIC packages.

PRODUCT HIGHLIGHTS
1. Single-Supply Operation. The AD5541 and AD5542 are fully
specified and guaranteed for a single 2.7 V to 5.5 V supply.
2. Low Power Consumption. These parts consume typically
0.625 mW with a 5 V supply and 0.375 mV at 3 V.
3. 3-Wire Serial Interface.
4. Unbuffered Output Capable of Driving 60 kΩ Loads. This
reduces power consumption because there is no internal
buffer to drive.
5. Power-On Reset Circuitry.
