AD5428YRUZ-REEL7

Digital To Analog Converters Overview

The AD5428YRUZ-REEL7 is a dual-channel, 8-bit multiplying 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 a 10 MHz reference multiplying bandwidth and supports an update rate of 21.3 MSPS. Key electrical specifications include ±0.25 LSB integral nonlinearity (INL), ±1 LSB differential nonlinearity (DNL), and a typical power consumption of 0.5 µA. It utilizes a 20-lead TSSOP package and functions within an extended temperature range of −40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The REEL7 designation indicates tape-and-reel packaging intended for automated surface-mount assembly. Confirm that the Y-grade variant meets the required extended temperature operating range of −40°C to +125°C for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when high-speed parallel data transfer is required alongside low power consumption. The AD5428 serves as a direct upgrade path for legacy AD7528 designs. Ensure the external reference voltage does not exceed the ±10 V input limit and verify that the system can accommodate the 20-lead TSSOP footprint.

Digital To Analog Converters Part Context

This part belongs to the AD5428/AD5440/AD5447 family of multiplying DACs. While the AD5440 offers 10-bit resolution and the AD5447 provides 12-bit resolution in a 24-lead package, the AD5428 specifically delivers 8-bit performance in a compact 20-lead TSSOP form factor.

Digital To Analog Converters Replacement Considerations

The AD5428 is documented as a functional upgrade for the AD7528. Designers replacing older components should verify pin compatibility and ensure that the new device's power supply requirements align with the existing circuit design.
