Dual Audio Power Amplifier

Leave a Comment
General Description:
The TA8211AH is dual audio power amplifier for consumer applications.  This IC provides an output power of 6 watts per channel  (at VCC = 20 V, f = 1 kHz, THD = 10%, RL = 8 Ω). 
It is suitable for power amplifier of TV and home stereo. 

Features:
  • High output power: Pout = 6 W/channel (Typ.) 
  •  (VCC = 20 V, RL = 8 Ω, f = 1 kHz, THD = 10%) 
  • Low noise: Vno = 0.14 mVrms (Typ.) 
  •  (VCC = 28 V, RL = 8 Ω, GV = 34dB, Rg = 10 kΩ, 
  •  BW = 20 Hz~20 kHz) 
  • Very few external parts 
  • Built in thermal shut down protector circuit 
  • Operating supply voltage range: VCC (opr) = 10~30 V (Ta = 25°C)

General Descrioption:
The TDA2611A is a monolithic integrated circuit in a 9-lead single in-line (SIL) plastic package with a high supply voltage audio amplifier. 
Special features are:

  • possibility for increasing the input impedance
  • single in-line (SIL) construction for easy mounting
  • very suitable for application in mains-fed apparatus
  • extremely low number of external components
  • thermal protection
  • well defined open loop gain circuitry with simple quiescent current setting and fixed integrated closed loop gain.

One Chip AM/FM Radio with Audio Power Amplifier

Leave a Comment
Description:
The integrated circuit TDA1083 includes, with exception of the FM front end, a complete AM-/FM-radio-circuit with audio power amplifier. An internal Z-diode stabilizes the supply voltage at VS 13 V, which allows with the aid of a resistor and a rectifier, the circuit to be driven by a higher external supply voltage.

Features:
  • Large supply voltage range VS = 3 to 12 V
  • High AM-Sensitivity
  • Limiting threshold voltage Vi = 50 V
  • Audio output power P0 = 0.7 W
  • AFC-connection for VHF-tuner
  • AM-FM switching without high frequency voltages

Applications:
  • AM-/FM- and audio-amplifier
