AD5446YRM-REEL

Digital To Analog Converters Overview

The AD5446YRM-REEL is a 14-bit current output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates on a single 2.5 V to 5.5 V supply and features a 12 MHz multiplying bandwidth with a 2.7 MSPS update rate. The device utilizes a double-buffered, 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Packaged in a 10-lead MSOP, it supports ±10 V reference inputs and includes an integrated feedback resistor. Key static performance metrics include a relative accuracy of ±2 LSB and a total unadjusted error of ±4 LSB.

Digital To Analog Converters Feature Summary

• Double-buffered 3-wire serial interface (SPI/QSPI/Microwire)
• Single-supply operation from 2.5 V to 5.5 V
• Integrated 9 kΩ feedback resistor (typical)

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 REEL suffix indicates tape-and-reel packaging for automated assembly. Confirm RoHS compliance status as specifications may vary by manufacturing revision. Ensure the extended temperature range (-40°C to +125°C) matches the specific Y-subgrade variant requirements for the target environment.

Digital To Analog Converters Selection Notes

Select this component when high-speed 4-quadrant multiplication is required alongside 14-bit precision. The external reference input allows flexibility in setting full-scale output current. Consider the need for an external operational amplifier to convert the current output to voltage if a voltage output mode is desired.

Digital To Analog Converters Part Context

This part belongs to the AD5444/AD5446 family of high-bandwidth multiplying DACs. It shares pin compatibility with the AD5425, AD5426, AD5432, and AD5443 series, facilitating design upgrades from lower-resolution devices within the same package footprint.

Digital To Analog Converters Replacement Considerations

The AD5444 serves as a pin-compatible alternative offering 12-bit resolution. For higher resolution needs, the AD5453 provides 16-bit performance within the same package family.
