RF Receivers Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct package type and temperature rating. Confirm that the I2C interface requirements match your system's bus specifications. Check moisture sensitivity levels and reflow soldering profiles if surface-mount assembly is planned. Ensure the operating voltage range aligns with your power supply design. Validate frequency coverage against your specific regional regulatory requirements.

RF Receivers Selection Notes

Select this component when low power consumption and high sensitivity are critical for ASK or FSK applications. The integrated I2C interface reduces external component count compared to parallel interface alternatives. Consider the wide operating temperature range for industrial or automotive environments. Evaluate the 12-TQFN package size against available PCB space constraints. Ensure the target frequency band falls within the 290 MHz to 960 MHz operational range.

RF Receivers Part Context

This device belongs to the Maxim Integrated line of RF receivers, now part of Analog Devices.
