New TPA3118 TPA3116 TPA3130 Stereo Class D Amplifier BTL

| | , , ,

TPA3116 TPA3118 and TPA318 and TPA3130 BTL Class D Stereo Power Amplifier with 15+ 15W, 30 + 30W or 50 + 50W power supply of 4.5 to 26V with analog input. The TPA31XXD2 chip series are an efficient amplifier with digital power stage for power up to 100W in the mono version. The high efficiency of CI’s TPA3116 TPA3118 and TPA3130 make it widely used on portable devices such as mini portable boxes such as JBL CHARGE 3 (TPA3118D2) and HARMAN KARDON ONYX STUDIO (TPA3116D2) and can be powered by batteries.

TPA31xxd2 features an advanced PLL oscillator circuit with multiple switching switching frequencies to avoid interference in AM. This also together with
The master or slave option, making it possible to synchronize multiple devices.

The TPA31xxD2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100 W / 2 Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without external heat sink on a single layer PCB. The TPA3118D2 can even run 2 × 30 W / 8 Ω without heat sink on a dual
layer PCB. If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ω with a small heatsink attached to its top side PowerPAD. All three devices share the same footprint enabling a single
PCB to be used across different power levels. The TPA31xxD2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences; this is achieved together with an option of either master or slave option, making it possible to synchronize multiple devices. The TPA31xxD2 devices are fully protected against faults with short-circuit protection and thermal protection as well as overvoltage, undervoltage, and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.

See our project of amplifiers and power Supply

The TPA31xxD2 device is a highly efficient Class D audio amplifier with integrated 120m Ohms MOSFET that allows output currents up to 7.5 A. The high efficiency allows the amplifier to provide an excellent audio performance without the need for a bulky heat sink.
The device can be configured for either master or slave operation by using the SYNC pin. This helps to prevent audible beats noise

Gain Setting and Master and Slave TPA3116D2, TPA3118D2 or TPA3130D2

The gain of the TPA31xxD2 family is set by the voltage divider connected to the GAIN/SLV control pin. Master or Slave mode is also controlled by the same pin. An internal ADC is used to detect the 8 input states. The first four stages sets the GAIN in Master mode in gains of 20, 26, 32, 36 dB respectively, while the next four stages sets the GAIN in Slave mode in gains of 20, 26, 32, 36 dB respectively. The gain setting is latched during power-up and cannot be changed while device is powered. Table 1 lists the recommended resistor values and the state and gain:
In our application we are using Master Configuration with 26dB gain and 30K input impedance, but if you prefer, you can use another resistor configuration.

AM Avoidance EMI Reduction TPA3116, TPA3118 or TPA3130 amp
To reduce interference in the AM radio band, the TPA3116D2 has the ability to change the switching frequency via AM<2:0> pins. The recommended frequencies are listed in Table. The fundamental frequency and its second harmonic straddle the AM radio band listed. This eliminates the tones that can be present due to the switching frequency being demodulated by the AM radio.

About Amplifier Circuit with chip TPA3116D2, TPA3118D2 or TPA3130D2

You must choose the IC according to your power need, each of a chip will have a maximum power limit. Our circuit is configured for 26dB gain in BTL mode. The coil should be 10uh and at least 5 amps. The circuit around the PMBT3906 transistor is responsible for the MUTE when switching on and off, avoiding the crack in the sound box. The components are SMD 0805, which are not difficult to weld. Also if you prefer you can order the JLCPCB the board already with the soldered SMD components.
