AD5451YUJZ-REEL7

Digital To Analog Converters Overview

The AD5451YUJZ-REEL7 is a 10-bit, single-channel current-output digital-to-analog converter (DAC) from Analog Devices. It operates on a 2.5 V to 5.5 V supply and supports a 2.7 MSPS update rate with a 12 MHz multiplying bandwidth. The device features an R-2R architecture, ±0.25 LSB relative accuracy, and ±0.5 LSB differential nonlinearity. It utilizes a double-buffered 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Key electrical parameters include a 100 ns settling time, external reference input range of ±10 V, and typical power consumption below 0.4 μA.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'REEL7' against the manufacturer's ordering guide to confirm tape and reel packaging quantities. Confirm that the 'Y' designation matches the required extended temperature range of –40°C to +125°C for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution is required alongside high-speed updating capabilities up to 2.7 MSPS. Ensure the design accommodates an external voltage reference within the ±10 V range. Verify that the system logic levels align with the specified VIH and VIL thresholds for the chosen supply voltage.

Digital To Analog Converters Part Context

This part belongs to the AD5450/AD5451/AD5452/AD5453 family of high-bandwidth multiplying DACs. While sharing identical pinouts and core architectures, the AD5451 specifically provides 10-bit resolution, distinguishing it from the 8-bit AD5450, 12-bit AD5452, and 14-bit AD5453 variants.

Digital To Analog Converters Replacement Considerations

Pin-compatible substitutes within the same family include the AD5450, AD5452, and AD5453. Note that these alternatives offer different resolutions (8-bit, 12-bit, and 14-bit respectively) which may impact precision requirements.
