GENERAL DESCRIPTION
The AD5541 and AD5542 are single, 16-bit, serial input,
voltage output DACs that operate from a single 5 V
±
10%
supply.
The AD5541 and AD5542 utilize a versatile 3-wire interface that
is compatible with SPI, QSPI, MICROWIRE, and DSP inter-
face 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 generating a
±

output swing. The AD5542 also includes Kelvin sense
connections for the reference and analog ground pins to reduce
layout sensitivity.
The AD5541 and AD5542 are available in an SO package.
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 k
loads.
This reduces power consumption as there is no internal buffer
to drive.
5. Power-On Reset circuitry.
