AD5440YRUZ-REEL7

Digital To Analog Converters Overview

The AD5440YRUZ-REEL7 is a dual-channel, 10-bit digital-to-analog converter (DAC) from Analog Devices. It features a parallel interface and operates on a single 2.5 V to 5.5 V supply. The device provides current outputs with an update rate of 21.3 MSPS and a multiplying bandwidth of 10 MHz. Static performance includes ±0.5 LSB relative accuracy and ±1 LSB differential nonlinearity. It utilizes an external reference input range of ±10 V and incorporates an integrated feedback resistor for voltage output configurations. The component is housed in a 24-lead TSSOP package and supports operation across an extended temperature range of −40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the reel packaging format required for automated assembly processes. Confirm that the Y suffix indicates compliance with the extended industrial temperature range specifications (-40°C to +125°C). Ensure compatibility with the 24-lead TSSOP footprint during PCB layout verification.

Digital To Analog Converters Selection Notes

Select this component when a high-speed, low-power dual-channel DAC is required for battery-operated systems. The 10-bit resolution balances precision with speed for applications like programmable gain stages. Verify that the system can accommodate the parallel interface timing requirements and that an external reference voltage within the ±10 V range is available.

Digital To Analog Converters Part Context

This part belongs to the AD5428/AD5440/AD5447 family of multiplying DACs. It serves as the 10-bit variant within this series, positioned between the 8-bit AD5428 and the 12-bit AD5447. All members share identical pinouts and functional architectures, differing primarily in resolution and associated linearity specifications.

Digital To Analog Converters Replacement Considerations

The AD5440YRU is a direct replacement option, though it may be obsolete. Other family members like the AD5447 offer higher resolution but require verification of interface and performance compatibility.
