AD5443YRMZ-REEL

Digital To Analog Converters Overview

The AD5443YRMZ-REEL is a 12-bit current-output digital-to-analog converter (DAC) from Analog Devices, part of the AD5426/AD5432/AD5443 family. It operates on a single 2.5 V to 5.5 V supply and features a high-speed 50 MHz serial interface compatible with SPI, QSPI, Microwire, and DSP standards. The device offers a 10 MHz multiplying bandwidth and a maximum update rate of 2.5 MSPS. Key performance metrics include an integral nonlinearity (INL) of ±1 LSB and a differential nonlinearity (DNL) of -1/+2 LSB. It incorporates power-on reset with brownout detection, daisy-chain capability, and readback functions.

Digital To Analog Converters Feature Summary

• 12-bit resolution with guaranteed monotonicity and ±1 LSB INL
• High-speed 50 MHz serial interface supporting multiple protocols
• 10 MHz reference multiplying bandwidth for 4-quadrant multiplication
• Low glitch energy (< 2 nV-s) and extended temperature range (-40°C to +125°C)

Digital To Analog Converters Applications

• Portable battery-powered applications
• Waveform generators
• Programmable amplifiers and attenuators
• Digitally controlled calibration
• Ultrasound systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing. Confirm the 'Y' grade corresponds to the extended industrial temperature range of -40°C to +125°C. Ensure the order matches the 12-bit AD5443 variant rather than the 8-bit or 10-bit counterparts in the same package.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed serial control and precise current output. The external reference input allows flexibility in setting full-scale output current. An integrated feedback resistor simplifies voltage output configurations when used with an external amplifier. Ensure the system logic levels are compatible with the specified VIH and VIL thresholds.

Digital To Analog Converters Part Context

This device belongs to a pin-compatible family including the 8-bit AD5426 and 10-bit AD5432. All three share the same 10-lead MSOP footprint and functional block diagram, differing primarily in resolution and linearity specifications. This allows for design scalability across different precision requirements without changing the PCB layout.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the AD5426 (8-bit) and AD5432 (10-bit), which offer identical pinouts and interfaces but lower resolution. For higher resolution needs, other ADI DAC families must be evaluated as no direct 14-bit or 16-bit pin-compatible alternative exists in this specific series.
