GENERAL DESCRIPTION

The AD5541A is a single, 16-bit, serial input, unbuffered voltage

output digital-to-analog converter (DAC) that operates from a

single 2.7 V to 5.5 V supply.

monotonic, providing ±1 LSB INL accuracy at 16 bits without

adjustment over the full specified temperature range of −40°C

to +125°C. The AD5541A is available in a 3 mm × 3 mm, 10-lead

LFCSP and 10-lead MSOP. The AD5541A-1 is available in a

3 mm × 3 mm, 8-lead LFCSP.

Offering unbuffered outputs, the AD5541A achieves a 1 µs set-

tling time with low power consumption and low offset errors.

Providing low noise performance of 11.8 nV/√Hz and low

glitch, the AD5541A is suitable for deployment across multiple

end systems.

The AD5541A uses a versatile 3-wire interface that is compatible

with 50 MHz SPI, QSPI™, MICROWIRE™, and DSP interface

standards.
