GENERAL DESCRIPTION
The AD5541/AD5542 are single, 16-bit, serial input, voltage
output digital-to-analog converters (DACs) that operate from
a single 5 V ± 10% supply.
The AD5541/AD5542 utilize a versatile 3-wire interface that is
compatible with SPI, QSPI™, MICROWIRE™, and DSP interface
standards.
These DACs provide 16-bit performance without any adjust-
ments. The DAC output is unbuffered, which reduces power
consumption and offset errors contributed to by an output buffer.
The AD5542 can be operated in bipolar mode, which generates
a ±V
output swing. The AD5542 also includes Kelvin sense
REF
connections for the reference and analog ground pins to reduce
layout sensitivity.
The AD5541/AD5542 are available in SOIC packages.

PRODUCT HIGHLIGHTS
1.
Single-Supply Operation. The AD5541 and AD5542 are
fully specified and guaranteed for a single 5 V ± 10% supply.
2.
Low Power Consumption. These parts consume typically
1.5 mW with a 5 V supply.
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.
