Product Details

The AD5541A is a single, 16-bit, serial input, unbuffered voltage output digital-to-analog converter (DAC) that operate from a single 2.7 V to 5.5 V supply.

The DAC output range extends from 0 V to VREF 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 a 50 MHz SPI, QSPI™, MICROWIRE™, and DSP interface standards.

Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
