AD5428YRUZ

Digital To Analog Converters Overview

The AD5428YRUZ is a dual-channel, 8-bit CMOS 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 a reference multiplying bandwidth of 10 MHz and an update rate of 21.3 MSPS. Key specifications include ±0.25 LSB relative accuracy, ±1 LSB differential nonlinearity, and a typical power consumption of 0.7 µA. It supports 4-quadrant multiplication and includes a readback function for the DAC register contents.

Digital To Analog Converters Feature Summary

• Dual-channel 8-bit resolution with 10 MHz multiplying bandwidth
• Parallel data interface with 21.3 MSPS update rate
• Low power consumption: 0.7 µA typical at 25°C
• Integrated feedback resistors for voltage output configuration

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 specific package variant, as the AD5428 uses a 20-lead TSSOP while related models in the series use different packages. Confirm that the Y suffix indicates the extended temperature range of −40°C to +125°C. Ensure compatibility with the required parallel interface timing and supply voltage levels before procurement.

Digital To Analog Converters Selection Notes

Select the AD5428YRUZ when an 8-bit resolution is sufficient for the application's linearity requirements. Choose this part over higher-resolution variants like the AD5447 if lower power consumption and cost are priorities. Ensure the design accommodates the parallel interface constraints and the external reference input range of ±10 V.

Digital To Analog Converters Part Context

The AD5428 serves as an upgrade to the legacy AD7528 component. It belongs to a family of high-bandwidth multiplying DACs that also includes the 10-bit AD5440 and the 12-bit AD5447. All devices share similar architectural features but differ in resolution and package pin counts.

Digital To Analog Converters Replacement Considerations

The AD5428 is explicitly listed as an upgrade for the AD7528. When replacing the AD7528, verify that the parallel interface timing and supply voltage requirements are compatible with the new CMOS-based architecture.
