TDA2005 Audio Amplifier 2x10w

2 comments

TDA2005 description:



The TDA2005 is a class B dual audio power amplifier in Multiwatt11 package specifically designed for car radio applications. Power booster amplifiers can be easily designed  using this device that provides a high current  capability (up to 3.5 A) and can drive very low  impedance loads (down to 1.6  in stereo  applications) obtaining an output power of more than 20 W (bridge configuration). TDA2005 Audio Amplifier 2x10w

TDA2005 features:

High output power:
Po = 10 + 10 W @ RL = 2 , THD = 10 %
Po = 20 W @ RL = 4 , THD = 10 %.
Protection against:

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
