Digital To Analog Converters Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing components. Confirm that the Y version meets the extended industrial temperature range requirements of –40°C to +125°C. Ensure compatibility with the 16-lead TSSOP footprint during procurement planning.

Digital To Analog Converters Selection Notes

Select this component for designs requiring high-speed current output with a parallel data bus. The AD5424 is suitable where 8-bit precision is sufficient but speed is critical. Consider the external reference input range of ±10 V when designing the reference circuitry. Verify that the system logic levels align with the specified VIH and VIL thresholds.

Digital To Analog Converters Part Context

This part belongs to the AD5424/AD5433/AD5445 family of CMOS multiplying DACs. It serves as an upgrade to the legacy AD7524, offering improved multiplying bandwidth performance. The device utilizes an R-2R ladder architecture and is designed for applications demanding low power consumption and fast settling times in a compact surface-mount package.

Digital To Analog Converters Replacement Considerations

The AD5424 is a direct pin-compatible replacement for the AD7524. Designers upgrading from older architectures should verify that the latched interface of the AD5424 does not conflict with existing transparent mode requirements in the host system.
