Unlike TDA7377-7379, The TDA7297 circuit is same even a pins# connection to PCB board.

► The TDA7297 is a 15+15W DUAL dual bridge amplifier specially designed for TV and Portable Radio applications. ► The TDA7292 is a class-AB dual 40+40 watts audio power amplifier assembled in a 11 PIN Multi-watt package, Split supply, High output power range at 40W + 40W into 8Ω with a power supply of VS = ☒8V. TDA7396 DataSheet TDA7391 Datasheet TDA7391/96 Price at PH WATCH the Video Info and connection diagramĤ0W/3.2ohms VS = 14.4 V, f = 1 kHz,d = 10 %Ģ6W/4ohms VS = 14.4 V, f = 1 kHz, d = 10 % To power-up, Connect the Pin4(CD) to ST-BY see the schematic info. The onboard clipping detector allows easy implementation of gain compression systems.Ĥ5W-65W/2ohms max, Best for Subwoofer system. The exclusive fully complementary output stage and the internal fixed gain configuration drop the external component count. The TDA739x is high power capability together with the possibility to operate either in DIFFERENTIAL INPUT MODE or SINGLE ENDED INPUT MODE makes it suitable for boosters and high-end car radio equipment. The TDA739x is not same to TDA737x but related to ClassAB 12Volts series, It is Zip11 pin and BRIDGE class-AB MONO audio power amplifier specially intended for car radio HighPower applications. WIDE SUPPLY VOLTAGE RANGE (6V -18V) MINIMUM EXTERNAL COMPONENTS NO SVR CAPACITOR NO BOOTSTRAP NO BOUCHEROT CELLS INTERNALLY FIXED GAIN STAND-BY MUTE FUNCTIONS SHORT CIRCUIT PROTECTION THERMAL OVERLOAD PROTECTION. Parallel Bridge type to Double the power and can hold 2 Ohms Load, Also can sustain a 20 Hz frequency for better Bass Output. Note: You need to replace from 47uf capacitor to 100uf connected to SVR PIN #6įor Advance Circuit I already Test.

TDA7379 Double-Bridge Type series without a PCB, You can double the output power by using two IC joint together to supply the load of speaker impedance, Its not adding wattage but it is stable for Low impedance like 2 Ohm load for great performance of Subwoofer 2 cone parallel. You can create TDA737x of yours as a home-made project like sample a video below. The Pin1,2 is for 1CH speaker no need Capacitor, also the 14 and 15 pin is for the 2CH speaker.įor me this is the best selection among 3, The connection is 3CH output which delivers the better sound output, User must make a filtered 2.1 signal preamp which separates the low pass filter(bass sound) and connect to IN BRIDGE, take a look at schematic above. The Pin input must 4,5, is connected to each other and 11,12 is connected also, In this connection, the output to the speaker is no need to connect to common ground. If you want to double the power out for big speaker, Yes it can be but the output becomes 2CH output. Note: The output decoupling capacitors(C9, C10, C11, C12) could be reduced to 1000μF if the 2Ω operation is not required. 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. 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 This 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
