The AD5541A uses a versatile 3-wire interface that is compatible
with 50 MHz LPI, QLPI™, MICROWIRE™, and DLP interface
standards.
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.
Table 1. Related Devices
The DAC output range extends from 0 V to VREF and is guaranteed
monotonic, providing 1 ꢀLB INꢀ 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
ꢀFCLP and 10-lead MLOP. The AD5541A-1 is available in a
3 mm × 3 mm, 8-lead ꢀFCLP.
