GENERAL DESCRIPTION  
CS  
16-BIT DATA LATCH  
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.  
PRODUCT HIGHLIGHTS  
1. Single Supply Operation.  
The AD5541 and AD5542 are fully specified and guaranteed  
for a single 5 V ± 10% supply.  
The AD5542 can be operated in bipolar mode generating a  
±VREF output swing. The AD5542 also includes Kelvin sense  
connections for the reference and analog ground pins to reduce  
layout sensitivity.  
2. Low Power Consumption.  
These parts consume typically 1.5 mW with a 5 V supply.  
3. 3-Wire Serial Interface.  
The AD5541 and AD5542 are available in an SO package.  
4. Unbuffered output capable of driving 60 kloads.  
This reduces power consumption as there is no internal buffer  
to drive.  
5. Power-On Reset circuitry.
