![]() ![]() The 4 Pin 1,2,14 and 15 output power is also separated from each other and the common line after the speaker is connected to ground (negative power supply). You can select the number 1- Quad Stereo. The design of the schematic diagram above is the input signal Pin number 4,5,11,12 is separated each. There are (3) three selection want to use this IC- 4CH, 2CH, 2.1CH speaker output connection. The TDA7379 or TDA7377 or TDA7375 is compatible each other because it is same on PINOUT and parts, You can use as replacement any of these 3, You can see the diagram below shows. Schematic diagram of TDA737x series is same To Power-up the ic must connect the ST_BY to Vs+ supply. ![]() ![]() Highest power performances with an extremely reduced component count. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantee the ![]() The TDA737x is a new technology class AB audio processor amplifier able to work either is DUAL BRIDGE or QUAD SINGLE ENDED configuration. MINIMUM EXTERNAL COMPONENTS COUNT -NO BOOTSTRAP CAPACITORS -NO BOUCHEROT CELLS -INTERNALLY FIXED GAIN (26dB BTL) -ST-BY FUNCTION (CMOS COMPATIBLE)-NO AUDIBLE POP DURING ST-BY OPERATIONS-SOFT SHORT AT TURN-ON -THERMAL SHUTDOWN PROXIMITY -OUTPUT AC/DC SHORT CIRCUIT -OVERRATING CHIP TEMPERATURE WITH SOFT THERMAL LIMITER ![]()
