High-Output Power Amplifier
for Car Stereos (Po = 60 W typ.)
Overview
Higher output amplification of the car stereo has been
generally dependent on boosting voltage of the power
supply. The STK4067 supports low-load impedance and
is designed for up to 60 W of high output without the
need for a power supply voltage booster circuit.
Applications
• Power amplifier for car stereos
• Home karaoke systems
• Radio-cassette players
Features
• Superior heat sink capacity using IMST (insulated
metal substrate technology)
• Designed for high output while supporting low-load
impedance

• Supports sufficient amplifier configurations for high
power output
• Low-load impedance driver
Supports independent or parallel speaker connections
for low-load impedance driving.
• Low distortion

Compared with a monolithic IC, with a base
frequency of 100 Hz, the following is established:
secondary high frequency harmonics switches to
–58 dB, with third-order switching to –20 dB,
fourth-order to –45 dB, and fifth-order to –18 dB.
• High temperature operation
Provides guaranteed high output to the passenger
compartments protected interior even when operating
in excessive heat
• Compact heat sink mounting
Supports compact total-set packaging, occupying 1/3
the heat sink area compared of monolithic ICs, and
equipped with an 85°C temperature range and 110°C
guaranteed case temperature rating
• Low operating power supply voltage range (9 V to 16 V)
• Built-in muting circuit
Short attack time with muting quickly enabled
• Built-in protection circuits
Built-in thermal shutdown and overvoltage protector
