SA58632BS,118

Overview

The SA58632BS,118 is a two-channel audio amplifier in an HVQFN20 package. It provides power output of 2.2 W per channel with an 8 Ω load at 9 V supply. The internal circuit is comprised of two BTL (Bridge-Tied Load) amplifiers with a complementary PNP-NPN output stage and standby/mute logic. The SA58632 is housed in a 20-pin HVQFN package, which has an exposed die attach paddle enabling reduced thermal resistance and increased power dissipation.

Feature Summary

Low junction-to-ambient thermal resistance using exposed die attach paddle
Gain can be fixed with external resistors from 6 dB to 30 dB
Standby mode controlled by CMOS-compatible levels
Low standby current < 10 μA

Applications

Professional and amateur mobile radio
Portable consumer products: toys and games
Personal computer remote speakers

Procurement Notes

Verify the component matches the exact part number SA58632BS,118 and the manufacturer NXP Semiconductors. Confirm the package type is HVQFN20 as specified in the ordering information table. Ensure the datasheet revision corresponds to Rev. 02 dated 4 March 2010 for accurate electrical characteristics and pin configurations.

Selection Notes

Select this amplifier when a low-power, two-channel audio solution is required for portable devices. Consider the BTL configuration for driving speakers without coupling capacitors or the SE configuration for headphones. Evaluate the thermal requirements based on the PCB heat spreader size, as the thermal resistance varies significantly depending on the copper area connected to the exposed paddle.

Part Context

The SA58632 is designed as a cost-effective audio amplifier for consumer electronics. It integrates protection features such as thermal shutdown and output short-circuit protection. The device operates within a wide supply voltage range, making it suitable for battery-powered applications where power efficiency and low quiescent current are critical design parameters.
