AZAD2102B  provide  a  Vibration-Spectrum  modulation  clock  for  PWM  Output.  This 
vibration frequency is around 10KHZ shift (+/- 5KHZ of Fpwm). 

The  advantage of  the small  size package (WCSP) makes AZAD2102B very  suitable  for 
mobile  phone  and  PDA  device  application.  And  the  Class-D  amplifier  structure  let 
AZAD2102B  to  have  highly  efficiency  power  consumption  than  Class-AB  amplifier. 
AZAD2102B  can  shrink  the  application  board,  reduce  system  cost,  and  external 
components. 

ESD  level  protection  I/O  embedded  in  AZAD2102B.  For  general  applications,  doesn’t 
need  to  add  extra  ESD  protection  device  (like  Varistors)  in  application  system  for 
AZAD2102B’s I/O.

 CMOS Technology 

 High Efficiency 85%

 Differential OP-amp Input 

 AZAD2102B provides Vibration-Spectrum Modulation clock for reduce EMI 

 Provide Mute function(set Mute_B to GND will go into Mute status) 

 For the input stage AZAD2102B built-in a 10Kohm resistors (Gain setting=29.5dB) 

 Maximum Battery Life and Minimum Heat 

 Efficiency With an 8-Ω Speaker: 

 3.5 mA Quiescent Current 

 Output Power at 10% THD 

 2.85Watts at AVdd=DVdd=5.0Volt, Rload=4Ω 

 1.45Watts at AVdd=DVdd=3.6Volt, Rload=4Ω 

 0.30Watts at AVdd=DVdd=3.0Volt, Rload=4Ω 

 1.75Watts at AVdd=DVdd=5.5Volt, Rload=8Ω 

 0.87Watts at AVdd=DVdd=3.6Volt, Rload=8Ω 

 0.41Watts at AVdd=DVdd=3.0Volt, Rload=8Ω 

 Eliminate Power on and Power-off “Pop” noise 

 A Fewer External Components 

 Optimized PWM Output Stage Eliminates LC Output Filter 

 Internally generate 290 kHz Switching Frequency to eliminate Capacitor and 

Resistor 

 Improve PSRR (–70 dB) and Wide Supply Voltage (3.0 V to 5.5 V) 

 Fully Differential Design Reduces RF Rectification 

 This chip has been built-in a very strong ESD protection. 

 System level ESD 4KV (IEC 61000-4-2 ESD Contact Level) 

 Wafer Chip Scale Package (WCSP) 

 TSSOP Package with Exposed Pad

17MB60 uses  a 6W  Class  D  Mono  Audio  Amplifers for from 26”  to  32”  TVs.  The 
TPA3113D2  is  a  6-W  (per  channel)  efficient, Class-D  audio  power  amplifier  for  driving 
bridged-tied stereo speakers. Advanced EMI Suppression Technology enables the use of 
inexpensive  ferrite  bead  filters  at  the  outputs  while  meeting  EMC  requirements. 
SpeakerGuard™  speaker  protection circuitry  includes  an  adjustable  power  limiter  and  a
DC detection circuit. The adjustable power limiter allows the user to set a "virtual" voltage 
rail lower than the chip supply to limit the amount of current through the speaker. The DC 
detect circuit measures the frequency and amplitude of the PWM signal and shuts off the 
output stage if the input capacitors are damaged or shorts exist on the inputs.

The  TPA3113D2  can  drive  stereo  speakers  as  low  as 4  Ω.  The  high  efficiency  of  the 
TPA3113D2, 87%, eliminates the need for an external heat sink when
playing music.

The  outputs  are  also  fully  protected  against  shorts  to GND,  VCC,  and  output-to-output. 
The short-circuit protection and thermal protection includes an auto-recovery feature.
