47 Watt 4-channel Audio Power Circuit Diagram

Overview:

The TB2903HQ is 4-ch BTL audio amplifier for car audio applications. This IC can generate higher power: POUT MAX = 47 W as it includes the pure complementary P-ch and N-ch DMOS output stage. It is designed to yield low distortion ratio for 4-ch BTL audio power amplifier, built-in standby function, muting function, and various kinds of protectors. Additionally, Off-set detector is built in. 

Features 

• High power output 
• POUT MAX (1) = 47 W (typ.) 
• VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) 
• Built-in standby switch function (pin 4) 
• Built-in muting function (pin 22) 
• Built-in Off-set detection function (pin 25) 
• Thermal shut down, overvoltage, out to GND, out to VCC, out to out short 
• Operating supply voltage: VCC (opr) = 9~18 V (RL = 4 Ω)

• Over-temperature protection 
• 48-Pin LQFP Package

Description

The TDA1400 is a one-channel, Amplifier Driver that uses Tripath’s proprietary Digital Power Processing  (DPPTM) technology. The TDA1400 offers higher integration over previous Tripath amplifiers driver  chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. The TDA1400 is typically configured as a single supply, bridged output. This makes the power supply requirements simpler and maximizes the output power for a given voltage rail. Additionally, the TDA1400 can be configured as a split supply, bridged amplifier, with the addition of some external components. The TDA1400 is capable of full range operation but the target application is subwoofers due to the high output power capability and single channel operation.

TDA8510J power amplifiers 2 x 13 + 26W

General Description for TDA8510J:

The TDA8510J is an integrated class-B output amplifier in a 17-lead single-in-line (SIL) power package. It contains a 26 W Bridge-Tied Load (BTL) amplifier and 2 × 13 W Single-Ended (SE) amplifiers. The device is primarily developed for multi-media applications and active speaker systems (stereo with subwoofer).

Features of TDA8510J:

• Requires very few external components
• High output power
• Low output offset voltage (BTL channel)
• Fixed gain
• Diagnostic facility (distortion, short-circuit and temperature detection)
• Good ripple rejection
• Mode select switch (operating, mute and standby)
• AC and DC short-circuit safe to ground and to VP
• Low power dissipation in any short-circuit condition
• Thermally protected
• Reverse polarity safe
• Electrostatic discharge protection
• No switch-on/switch-off plop
• Flexible leads
• Low thermal resistance
• Identical inputs (inverting and non-inverting)..
