STK4121V datasheet in PDF format, 92 KB, covering a hybrid audio power amplifier module from the Sanyo STK series. The sheet is expected to give pin assignments, maximum supply voltage, rated output and a sample application circuit. Bench use includes locating supply, input and output pins on an amplifier board, checking for DC offset on the outputs and confirming a shorted module before replacement. Fakes of STK hybrids are common, so compare the markings and test a new part under a current-limited supply first.
