AD5433YRUZ-REEL

Digital To Analog Converters Overview

The AD5433YRUZ-REEL7 is a 10-bit current output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.5 V to 5.5 V supply and features a fast parallel interface with a 17 ns write cycle, supporting an update rate of 20.4 MSPS. The device provides a 10 MHz multiplying bandwidth and includes power-on reset with brownout detection. It utilizes a CMOS submicron process for excellent 4-quadrant multiplication characteristics. The Y version supports an extended temperature range from –40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'REEL7' against the manufacturer's ordering guide to confirm tape-and-reel packaging quantities. Ensure the 'Y' suffix matches the required extended industrial temperature range of –40°C to +125°C. Confirm that the TSSOP-20 package aligns with the target PCB footprint requirements.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution is sufficient for the application. The parallel interface requires multiple data lines; ensure the host microcontroller or DSP has adequate GPIO availability. For voltage output applications, an external precision amplifier must be connected to the RFB pin. Verify that the system supply voltage remains within the 2.5 V to 5.5 V operating range.

Digital To Analog Converters Part Context

The AD5433 is part of the AD5424/AD5433/AD5445 family, which offers 8-, 10-, and 12-bit resolutions respectively. These devices are designed as upgrades to the older AD7524/AD7533/AD7545 series, providing improved multiplying bandwidth performance while maintaining pin compatibility across the family in both TSSOP and LFCSP packages.

Digital To Analog Converters Replacement Considerations

The AD5433 serves as a direct upgrade replacement for the AD7533. Both devices share similar functionality but differ in speed and process technology. When replacing legacy parts, verify that the new parallel interface timing constraints meet the system clock requirements.
