AD5453YRM-REEL7

Digital To Analog Converters Overview

The AD5453YRM-REEL7 is a 14-bit, high-bandwidth multiplying digital-to-analog converter (DAC) from Analog Devices. It features a current output architecture with a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports an external reference input range of ±10 V. Key performance metrics include a 12 MHz multiplying bandwidth, a maximum update rate of 2.7 MSPS, and a typical power consumption of less than 0.4 μA. The component is housed in an 8-lead MSOP package and is qualified for automotive applications.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. The 'Y' designation indicates an extended industrial temperature range of –40°C to +125°C. Confirm that the 'RMZ' or similar suffix corresponds to the MSOP package variant required for the design. Ensure compatibility with the intended serial communication protocol before procurement.

Digital To Analog Converters Selection Notes

Select this component when a high-resolution, low-power current-output DAC is required for portable or battery-operated systems. The AD5453 is suitable for applications demanding precise gain, offset, or voltage trimming due to its 14-bit accuracy. Consider the 12 MHz bandwidth for waveform generation tasks. Ensure the system can accommodate the ±10 V reference input requirement despite the low single-supply operation.

Digital To Analog Converters Part Context

The AD5453 is part of the AD5450/AD5451/AD5452/AD5453 family of CMOS multiplying DACs. These devices share pin-compatible layouts across different resolutions (8-bit, 10-bit, 12-bit, and 14-bit), facilitating design scalability. The AD5453 represents the highest resolution option in this series, offering 14-bit precision while maintaining the same low power profile and serial interface characteristics as its lower-resolution counterparts.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes within the same family include the AD5450 (8-bit), AD5451 (10-bit), and AD5452 (12-bit). Note that these alternatives offer lower resolution but may be suitable if 14-bit precision is not strictly required. Verify that any replacement maintains the required 14-bit linearity specifications if applicable.
