AD5450YUJZ-REEL7

Digital To Analog Converters Overview

The AD5450YUJZ-REEL7 is an 8-bit, high-bandwidth multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from a single 2.5 V to 5.5 V supply and features a serial interface compatible with SPI, QSPI, Microwire, and DSP standards. The device provides a current output with a reference input range of ±10 V and supports a maximum update rate of 2.7 MSPS. Key electrical specifications include an integral nonlinearity (INL) of ±0.25 LSB, a differential nonlinearity (DNL) of ±0.5 LSB, and a typical power consumption of less than 0.4 μA. It is housed in an 8-lead TSOT package and qualified for automotive applications.

Digital To Analog Converters Feature Summary

• 12 MHz multiplying bandwidth with 2.7 MSPS update rate
• External reference input supporting ±10 V despite single-supply operation
• Low power consumption (<0.4 μA typical) with power-on reset and brownout detect

Digital To Analog Converters Applications

• Portable battery-powered applications
• Waveform generators and analog processing
• Programmable amplifiers, attenuators, and filters
• Digitally controlled calibration and voltage trimming

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YUJZ-REEL7' against the manufacturer's ordering guide to confirm the package type (TSOT-8), temperature range (-40°C to +125°C), and tape-and-reel quantity. Ensure compatibility with the system's serial clock frequency limits (max 50 MHz) and logic voltage levels (2.5 V to 5.5 V). Confirm that the external reference voltage does not exceed the ±12 V absolute maximum rating.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy requirements. The AD5450 is suitable for designs requiring low power consumption and high-speed updating up to 2.7 MSPS. Consider the AD5451, AD5452, or AD5453 if higher resolution (10, 12, or 14 bits) is needed, as they share pinouts and interfaces but offer different accuracy specifications.

Digital To Analog Converters Part Context

The AD5450 is part of the AD5450/AD5451/AD5452/AD5453 family of CMOS multiplying DACs. These devices are designed for applications requiring precise analog signal generation and control. The family shares a common serial interface and functional block diagram, differing primarily in resolution and associated linearity specifications. The AD5450 specifically targets cost-sensitive or lower-resolution applications within this high-performance series.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include AD5451 (10-bit), AD5452 (12-bit), and AD5453 (14-bit). When substituting, verify that the increased resolution meets the system's accuracy needs and that the updated INL/DNL specifications align with the design margins. Other packages such as MSOP or LFCSP may be available for higher bit counts.
