AD5444YRM-REEL

Digital To Analog Converters Overview

The AD5444YRM-REEL is a 12-bit, high-bandwidth multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features a current output architecture with a 12 MHz reference multiplying bandwidth and supports update rates up to 2.7 MSPS. The device operates on a single 2.5 V to 5.5 V supply and accepts ±10 V reference inputs. It utilizes a double-buffered 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Key electrical specifications include an INL of ±0.5 LSB, guaranteed monotonicity, and typical current consumption of 0.4 µA. The component is housed in a 10-lead MSOP package.

Digital To Analog Converters Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging for automated assembly. Confirm the Y suffix corresponds to the extended industrial temperature range (-40°C to +125°C). Ensure compatibility with the 10-lead MSOP footprint during PCB design. Check for RoHS compliance status as per the specific manufacturing lot documentation.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed 4-quadrant multiplication or precise current control. The 12-bit resolution suits general-purpose analog processing where 14-bit precision (AD5446) is unnecessary. Consider the external amplifier requirements for converting the current output to voltage, noting the internal RFB value typically ranges from 7 kΩ to 11 kΩ.

Digital To Analog Converters Part Context

This part belongs to the AD5444/AD5446 family of CMOS current-output DACs. It is pin-compatible with the AD5425, AD5426, AD5432, and AD5443 series. The AD5444 serves as the 12-bit counterpart to the 14-bit AD5446 within this product line, sharing identical pinouts and interface protocols.

Digital To Analog Converters Replacement Considerations

Pin-compatible substitutes include the AD5446 (14-bit), AD5425 (8-bit), AD5426 (10-bit), AD5432 (10-bit), and AD5443 (12-bit). Verify that the replacement matches the required resolution and temperature grade.
