AN17823A

Overview

The AN17823A is a silicon monolithic bipolar IC designed as a BTL 4.0 W × 1-channel power amplifier with standby and volume functions. It operates within a supply voltage range of 3.5 to 13.5 V and dissipates up to 1.2 W at 70°C ambient temperature. The device utilizes a SIL 9-pin plastic package (HSIP009-P-0000E) featuring a power type with fin for thermal management. Pin assignments include dedicated inputs, outputs, ground connections, and control terminals for standby and volume adjustment.

Feature Summary

• Integrates bridge-tied load (BTL) power amplification with built-in standby and volume control capabilities.
• Constructed using silicon monolithic bipolar technology for robust performance.
• Features a specialized SIL 9-pin plastic package with an integrated heat-dissipating fin structure.

Applications

• Low frequency amplifier circuits
• General electronic equipment
• Household appliances

Procurement Notes

Verify the current lifecycle status via Panasonic's official semiconductor website before procurement, as the datasheet indicates maintenance or discontinuation stages. Confirm that the HSIP009-P-0000E package code matches your design requirements. Ensure compliance with export control laws if applicable. Consult sales staff for special applications beyond standard general electronics.

Selection Notes

Select this component for low-frequency audio applications requiring a single-channel BTL output. Verify that the operating supply voltage remains between 3.5 V and 13.5 V. Consider the 1.2 W power dissipation limit when designing thermal solutions, particularly at ambient temperatures up to 70°C. The integrated volume and standby functions reduce external component count compared to basic amplifier ICs.

Part Context

This part belongs to Panasonic's lineup of silicon monolithic bipolar ICs intended for standard applications such as office equipment, communications gear, and measuring instruments. It is distinct from wireless modules like the PAN series or automotive capacitors, focusing specifically on analog signal amplification in consumer and industrial electronics.

Replacement Considerations

No public substitute part numbers are documented in the provided source material. Users should consult Panasonic directly for cross-reference information or updated product standards.
