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.
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 +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.
