AD5428YRU

Digital To Analog Converters Overview

The AD5428YRU is a dual-channel, 8-bit CMOS multiplying digital-to-analog converter (DAC) in a 20-lead TSSOP package. It features a parallel interface and operates from a 2.5 V to 5.5 V supply. Key electrical parameters include a 10 MHz reference multiplying bandwidth, a 21.3 MSPS update rate, and an output voltage settling time of 15 ns typical. The device offers ±0.25 LSB relative accuracy and ±1 LSB differential nonlinearity. It supports a ±10 V reference input range and includes a readback function for DAC register contents.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'Y' indicates the extended temperature range of −40°C to +125°C. Confirm the package type is the 20-lead TSSOP (RU). Ensure the ordering code matches the exact resolution variant required, as this part number corresponds specifically to the 8-bit model within the family.

Digital To Analog Converters Selection Notes

Select this component when a high-speed, low-power dual-channel DAC is needed for battery-operated devices. The 8-bit resolution suits applications where cost and power are critical but moderate precision is acceptable. Verify that the external amplifier can handle the capacitive load and that the system requires a parallel interface rather than serial communication.

Digital To Analog Converters Part Context

The AD5428 serves as an upgrade to the AD7528, offering improved performance in a smaller footprint. It belongs to a family including the 10-bit AD5440 and 12-bit AD5447, which share similar architectures but differ in resolution and pin count (24-lead TSSOP). All variants utilize the same CMOS submicron process for high bandwidth and low power consumption.

Digital To Analog Converters Replacement Considerations

The AD7528 is a direct legacy replacement target, though it lacks the integrated feedback resistor and readback features. For higher resolution needs, consider the AD5440 (10-bit) or AD5447 (12-bit), noting the change to a 24-lead package.
