LA1837M-MPB-E

Overview

The LA1837M-MPB-E is a single-chip AM/FM tuner integrated circuit manufactured by onsemi. Designed for electronic tuning applications in home audio equipment, this component integrates AM and FM intermediate frequency (IF) circuits along with multiplex decoding functions. It operates within a supply voltage range of 6 V to 50 V and supports surface-mount installation in an S596 package. The device features a quiescent current consumption between 6 mA and 50 mA and can dissipate up to 800 mW of power. It is rated for operation across a temperature range of -30°C to +80°C.

Feature Summary

• Integrates AM and FM IF circuits with multiplex decoding for complete tuning functionality
• Supports electronic tuning systems in consumer audio hardware
• Utilizes surface-mount packaging for compact board integration

Applications

• Home AM/FM radio tuners
• Electronic tuning modules for audio receivers
• Consumer audio equipment requiring integrated RF processing

Procurement Notes

Verify the specific suffix 'MPB-E' against the official datasheet to confirm pinout compatibility and RoHS compliance status. Confirm that the S596 package dimensions match your PCB footprint requirements. Check for end-of-life notifications or discontinuance alerts from onsemi, as availability may be restricted. Ensure that the operating voltage and thermal dissipation limits align with your system design constraints before procurement.

Selection Notes

Select this component when a monolithic solution for AM/FM reception is required to minimize bill of materials complexity. Consider the S596 package size relative to available board space. Evaluate the 6 V to 50 V input range against your system's power supply architecture. Verify that the integrated multiplex decoding meets the signal processing needs without requiring external demodulation stages.

Part Context

This part belongs to the family of single-chip tuner ICs developed for home audio applications. It consolidates multiple RF and IF stages into one package, reducing the need for discrete components typically used in traditional tuner designs. The integration simplifies the schematic layout and assembly process for manufacturers of consumer electronics.
