TA8268H Datasheet – 4Ch, Audio Power Amplifier – Toshiba
4-Channel Audio Power Amplifier.
TA8268H overview
The TA8268H is a 4-Channel Audio Power Amplifier. made by Toshiba, supplied in a ZIP 25 Pin package. The absolute maximum ratings table on this page lists the 7 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the TA8268H pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The TDA7375 is a new technology class AB car radio amplifier able to work either in DUAL BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with extremely reduced component count. The on-board clip detector simplifies gain compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car.
