AD5541
ADI AD5541 16-bit serial-input voltage-output DAC with a buffered output, guaranteed monotonicity and a low power consumption, in an 8-lead SOIC.
The AD5541 is a single-channel, 16-bit, serial-input voltage-output digital-to-analog converter from ADI that delivers a monotonic, low-glitch output for a precision setpoint, a calibration or a control application. The part uses a thin-film R-2R ladder and an on-chip output amplifier that settles to a 16-bit level in a fraction of a microsecond, so a control loop can update a setpoint quickly while holding an integral and a differential nonlinearity the datasheet guarantees. The output is a buffered voltage that spans the full reference range, and the reference input accepts a wide range, so a designer can scale the output to the system without an external gain stage. The 16-bit data is loaded through a simple three-wire serial interface, which minimizes the digital routing to an isolated or a remote node, and the device includes a power-on reset that clears the output to a known state. The part runs from a single 2.7 V to 5.5 V supply with a low power consumption, which suits a portable or a loop-powered instrument. Typical applications include a precision setpoint in an industrial control loop, a programmable voltage or current source, a digital calibration or trim circuit, an optical or a laser bias control and a medical or a scientific instrument. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the reference and the output range and plan the layout.
FAE Professional Review
The AD5541 is a compact 16-bit voltage-output DAC that settles quickly and holds a guaranteed monotonicity, which suits a precision setpoint or a calibration path. The three-wire serial interface keeps the digital side simple, and the buffered output removes an external gain stage. Choose a low-drift reference and keep the reference and the output decoupling close, because the accuracy depends on them.

Frequently Asked Questions
What projects suit the AD5541?
It suits a precision setpoint, a calibration or a bias-control path that needs a stable, monotonic 16-bit voltage in a small package, updated through a simple serial interface.
Confirm the reference and the output range for your design.
How do I get a stable output?
Use a low-drift reference, decouple it close to the pin and keep the output and the ground return short. The output accuracy and the temperature drift depend mainly on the reference and the layout, not on the DAC alone.
Read the signal-chain design notes.
Is the DAC genuine and documented?
BeiLuo supplies factory-traceable AD5541 converters with an import declaration, certificate of origin and RoHS file on every order. Stock is normally available and the datasheet downloads from this page.
