MAX2175ETM/V+T

Overview

The MAX2175ETM/V+T is an automotive-grade RF tuner IC from Analog Devices/Maxim Integrated, designed for direct conversion of RF signals to digital bits. It operates within a supply voltage range of 2.7V to 3.6V and functions across a temperature range of -40°C to +125°C. The component is housed in a 40-lead TQFN package (7x7 mm) with an exposed pad. It features integrated low-noise amplifiers, mixers, and analog-to-digital converters, supporting multiple wireless standards including FM, DAB, and DRM.

Feature Summary

• Direct conversion architecture converts RF signals directly to digital data streams without intermediate frequency stages.
• Integrated automatic gain control and DC offset cancellation ensure stable signal processing under varying conditions.
• Automotive qualification ensures reliability and performance stability across extreme environmental temperatures.

Applications

• FM radio reception systems
• Digital Audio Broadcasting (DAB) receivers
• DRM (Digital Radio Mondiale) tuners

Procurement Notes

Verify current availability status as the component may be subject to limited supply or discontinuation notices. Confirm that the ordering suffix corresponds to the required tape-and-reel packaging configuration. Ensure compatibility with existing board layouts regarding the 40-TQFN footprint and thermal pad requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high integration and low power consumption in automotive audio environments. Consider the specific frequency bands supported by the internal synthesizer and filter configurations. Evaluate the interface protocol compatibility with the host microcontroller for digital output data handling.

Part Context

This part belongs to the MAX2175 family of RF-to-bits tuners. It shares architectural similarities with other Maxim Integrated direct-conversion tuners but is distinctively optimized for automotive grade specifications and multi-standard support including legacy FM and modern digital broadcasting formats.
