LA1828-S-E

Overview

The LA1828-S-E is a single-chip tuner integrated circuit designed for portable radio and cassette recorder applications. It integrates AM RF amplifier, mixer, oscillator, IF amplifier, and FM-FE/FM-IF circuits. The device includes a built-in MPX-VCO that requires no ceramic oscillator or external adjustment components. It supports manual tuning operations for both amplitude modulation and frequency modulation bands within a standard voltage supply range.

Feature Summary

• Integrates complete AM and FM receiver front-end and intermediate frequency processing on a single chip
• Includes a built-in multiplex VCO eliminating the need for external ceramic oscillators
• Requires no internal adjustments due to factory-calibrated MPX-VCO design

Applications

• Portable AM/FM radios
• Cassette recorders with radio tuners
• Handheld audio devices requiring manual tuning

Procurement Notes

Verify the specific suffix '-S-E' against the manufacturer's current product status documentation. Confirm that the component meets the required operating voltage specifications for the target application. Ensure compatibility with existing PCB layouts and antenna interfaces before procurement.

Selection Notes

Select this component for designs requiring a compact, single-chip solution for AM and FM reception. It is suitable for battery-powered portable devices where space constraints limit discrete component usage. Verify that the manual tuning interface aligns with the user control requirements of the final product.

Part Context

This part belongs to Sanyo's line of single-chip tuner ICs intended for consumer audio electronics. It replaces older multi-chip solutions by consolidating RF and IF functions. The device is specifically engineered for cost-sensitive portable applications where integration density is critical.

Replacement Considerations

Check official substitution lists for direct replacements. Generic tuner ICs may not match the specific MPX-VCO integration or pinout configuration.
