AD5452YRM

Digital To Analog Converters Overview

The AD5452YRM is a 12-bit current output digital-to-analog converter (DAC) from Analog Devices Inc., part of the AD5450/AD5451/AD5452/AD5453 series. It features a multiplying bandwidth of 12 MHz and operates on a single supply voltage ranging from 2.5 V to 5.5 V. The device utilizes a double-buffered, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards, supporting an update rate of up to 2.7 MSPS. Key static performance metrics include a relative accuracy of ±0.5 LSB, differential nonlinearity of ±1 LSB, and a gain error of ±0.5 LSB. It includes an internal feedback resistor (RFB) and supports a reference input range of ±10 V.

Digital To Analog Converters Feature Summary

• 12-bit resolution with 12 MHz multiplying bandwidth
• Double-buffered 3-wire serial interface (SPI/QSPI/MICROWIRE compatible)
• Single-supply operation (2.5 V to 5.5 V) with ±10 V reference input capability
• Integrated RFB for temperature tracking and full-scale voltage output

Digital To Analog Converters Applications

• Portable battery-powered applications
• Waveform generators
• Programmable amplifiers and attenuators
• Digitally controlled calibration
• Ultrasound systems

Digital To Analog Converters Procurement Notes

Verify the package type matches the 'YRM' suffix, which corresponds to the 8-lead MSOP package as specified in the datasheet outline dimensions. Confirm that the order quantity aligns with standard manufacturing packaging formats. Ensure the operating environment falls within the extended temperature range of –40°C to +125°C if utilizing the Y-grade variant specifications.

Digital To Analog Converters Selection Notes

Select the AD5452YRM when a 12-bit resolution is required alongside high-speed updating capabilities up to 2.7 MSPS. It is suitable for designs needing 4-quadrant multiplication with a 12 MHz bandwidth. Consider this component over the AD5450 or AD5451 if higher precision than 8 or 10 bits is necessary, but lower complexity than the 14-bit AD5453 is preferred. Ensure the system can accommodate the 8-lead MSOP footprint.

Digital To Analog Converters Part Context

The AD5452 is one of four devices in a pin-compatible family including the 8-bit AD5450, 10-bit AD5451, and 14-bit AD5453. This design allows for easy upgrade paths in terms of resolution without changing the PCB layout significantly, provided the package options (TSOT or MSOP) are consistent across the selected variants.

Digital To Analog Converters Replacement Considerations

The AD5450, AD5451, and AD5453 are pin-compatible alternatives within the same series. For direct replacement, verify that the resolution difference (8, 10, or 14 bits) meets the application requirements. Other packages such as TSOT or LFCSP may require schematic and layout modifications.
