TDA8560Q Audio amplifier 2x40W

Leave a Comment

TDA8560Q general description:

Unfortunately, some of the proposed scheme in the network and even a scheme recommended by the developer (Philips), fail to achieve the desired result. As an example of how not to suggest that you include the TDA8560 material published on Online Soldering: Car Amplifier 2x40 Watt (I should note that everything except the input circuits and the number of points on diet, still deserves attention). the initial inclusion of IMS (at power up, the load is connected and there is no input signal) can throw you into a state of perplexity / mild shock (it depends on the degree of hope is for your TDA). Chip is unstable, there are noises when the input signal is amplified last weakly and passed with distortions. IC bypass surgery fixed resistor at the input, the other measures in consultation with the source device does not help. Why and what to do? Really caught Palen chip and will have to buy a new one? Not so fast! The fact that Philips did not include measures to prevent the self-excitation of the IC, but I think they know about it, but do not tell anyone (not good, gentlemen!) Rid chip excitement can (and should) in a way that is not described here. This is so far, my little secret. Usually TDA8560 include approximately recommend the following scheme: TDA8560Q Audio amplifier 2x40W

5Wx2 10Wx2 25Wx2 40Wx2 Dual BTL class-D power audio amplifier AD199x

Leave a Comment
GENERAL DESCRIPTION:
The AD199x is a two channel Bridge Tied Load (BTL)  switching audio power amplifier with integrated ∑∆ modulator.  The modulator accepts a 1Vrms input signal (maximum power)  and generates a switching waveform to drive speakers directly.  One of the two modulators can control both output stages  providing twice the current for single-channel applications. A digital, microcontroller-compatible interface provides control of reset, mute and PGA gain as well as output signals for thermal and over-current error conditions. The output stage can operate  from supply voltages ranging from 8V to 20V. The analog  modulator and digital logic operate from a 5V supply. 

  • AD1990: 5Wx2 (10Wx1) 
  • AD1992: 10Wx2 (20Wx1) 
  • AD1994: 25Wx2 (50Wx1) 
  • AD1996: 40Wx2 (80Wx1) 


FEATURES:
  • Integrated Stereo Modulator & Power Stage 
  • 0.005% THD+N 
  • 101.5dB Dynamic Range 
  • PSRR > 65 dB 
  • RDS-ON < 0.3 Ω (per transistor) 
  • Efficiency > 80% @ 5W/6 Ω 
  • EMI Optimized Modulator 
  • On-Off-Mute Pop Noise Suppression 
  • Short Circuit Protection 
  • Over-Temperature Protection 
  • Low Cost DMOS Process 

APPLICATIONS:
  • Flat Panel Televisions
  • Automotive Amplifiers 
  • PC Audio Systems 
  • Mini Components

2x40W Two-Channel Class AB Audio Power Amplifier IC

Leave a Comment
Overview

The STK402-000 series products are audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO's unique insulated metal substrate technology (IMST). SANYO has adopted a new low thermal resistance substrate in these products to reduce the package size by about 60% as compared to the earlier SANYO STK407-000 series.
