AD5424YRU

Digital To Analog Converters Overview

The AD5424YRU is an 8-bit CMOS digital-to-analog converter (DAC) featuring a parallel interface and current output architecture. It operates on a single 2.5 V to 5.5 V supply, supporting update rates up to 20.4 MSPS with a 17 ns write cycle. The device provides a 10 MHz multiplying bandwidth and ±1 LSB INL accuracy. Key features include data readback capability, power-on reset with brownout detection, and guaranteed monotonicity. It is housed in a 16-lead TSSOP package and supports extended industrial temperature ranges from –40°C to +125°C.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YRU' against the manufacturer's ordering guide to confirm the package type (TSSOP), temperature range (Industrial), and tape-and-reel packaging configuration. Ensure compatibility with system voltage levels and interface timing requirements before procurement.

Digital To Analog Converters Selection Notes

Select the AD5424YRU when 8-bit resolution is sufficient for the application. Compare against AD5433 (10-bit) and AD5445 (12-bit) if higher precision is required, noting that these variants share pinouts but differ in bit depth and accuracy specifications. Verify external reference voltage capabilities within the ±10 V range.

Digital To Analog Converters Part Context

The AD5424 serves as an upgrade to the legacy AD7524, offering improved multiplying bandwidth performance while maintaining a latched parallel interface. It belongs to a family of CMOS DACs designed for high-speed data conversion tasks requiring low power consumption and compact packaging solutions.

Digital To Analog Converters Replacement Considerations

The AD7524 is a direct predecessor; however, the AD5424 utilizes a latched interface and lacks transparent mode operation. Designers must verify interface timing differences when migrating from older architectures.
