STK433-870-E

4-channel class AB audio power IC

60W

4ch

Overview

The STK433-870-E is 60W×4 channels class-AB audio frequency power amplifier hybrid IC.

Applications

• Audio power amplifiers.

Features

• Pin-to-pin compatible outputs ranging from 60W to 80W

• Can be used to replace the STK433-000/-100 series (30W to 150W/2ch/class-AB), STK415-100Series (80W to

150W/2ch/class H) due to its pin compatibility of ch1/ch2. 2ch class AB (30W to 60W, THD=10%) : STK433-000 series 2ch class AB (80W to 150W, THD=10%) : STK433-100 series 2ch class H (80W to 150W, THD=10%) : STK415-100 series

• Compact package (64.0mm×31.1mm×9.0mm, 78.0mm×44.1mm×9.0mm)

• Output load impedance RL=6Ω, 8Ω supported.

• Allowable load shorted time: 0.3s

• Allows the use of predesigned applications for standby and mute circuits

[Remarks]

*1. For 1-channel operation *2. Unless otherwise specified, use a constant-voltage power supply to supply power when inspections are carried out. *3. The output noise voltage values shown are peak values read with a VTVM. Howe ver , an AC stabilized (50Hz)

power supply should be used to minimize the influence of AC primary side flicker noise on the reading.

*4. Use the designated transformer power supply circuit shown in the figure below for the measurement of allowable

load shorted time and output noise volt a ge.

*5. The impression voltage of ‘#13 (Stand-By) pin’ must not exceed the maximum rating. Power amplifier operates by

impressing voltage +2.5 to +5.5V to ‘#13 (Stand-By) pin’.

* Please connect -Pre VCC pin (#1 pin) with the stable minimum voltage and connect so that current does not flow in

by reverse bias.

* Thermal design must be implemented based on the conditions under which the customer’s end products are expected

to operate on the market.

* The case of this Hybrid-IC is using thermosetting silicon adhesive (TSE322SX). * Weight of HIC: 20.6g
