MAX2173ETL/V+

Overview

The MAX2173ETL/V+ is an RF-to-bits tuner designed for automotive Digital Audio Broadcast (DAB) applications. It integrates a direct conversion receiver architecture covering three frequency bands: FM (76–108 MHz), DAB L-band (168–240 MHz), and DAB S-band (1.452–1.492 GHz). The device operates within a supply voltage range of 2V to 36V and features a low quiescent current of 20µA. Packaged in a 40-pin TQFN (6x6 mm) with an exposed pad, it supports surface-mount assembly and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Integrates direct conversion receiver architecture for multi-band RF tuning
• Supports simultaneous coverage of FM, DAB L-band, and DAB S-band frequencies
• Automotive-grade qualification compliant with AEC-Q100 standards
• Features ultra-low power consumption with 20µA quiescent current

Applications

• Automotive DAB radio tuners
• Multi-standard broadcast receivers
• In-vehicle infotainment systems
• Digital audio broadcast front-end modules

Procurement Notes

Verify the exact ordering suffix and package variant when sourcing, as availability may vary by region. Confirm RoHS compliance status through official manufacturer documentation. Check for end-of-life notifications or discontinuance alerts prior to final design approval. Ensure the supplier provides valid traceability and authenticity guarantees for automotive-grade components.

Selection Notes

Select this component for designs requiring integrated multi-band reception without external mixers. Verify that the system layout accommodates the 40-TQFN package thermal requirements. Ensure the host processor interface matches the digital output specifications. Consider the AEC-Q100 qualification if deploying in harsh automotive environments.
