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.

Features

? Superior heat sink capacity using IMST (insulated metal substrate technology)

? Designed for high output while supporting low-load impedance

① RL = 1? 60 W typ. (EIAJ) 100 W (max.)

? RL = 2? 40 W typ. (EIAJ) 70 W (max.)

③ RL = 4? 23 W typ. (EIAJ) 40 W (max.)

? 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

THD = 0.025 typ. (VCC = 13.2 V, RL = 2?, Po = 10 W, f = 1 kHz)

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

Applications

? Power amplifier for car stereos

? Home karaoke systems

? Radio-cassette players
