TDA1015 Audio Amplifier 1x4W

Leave a Comment

TDA1015 general description:



The TDA1015 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4Ω load impedance. The very low applicable supply voltage of 3,6 V permits 6 V spplications.

TDA1015 features:



  • single in-line (SIL) construction for easy mounting
  • separated preamplifier and power amplifier
  • high output power
  • thermal protection
  • high input impedance
  • low current drain
  • limited noise behaviour at radio frequencies

TDA1015 reference data:



  • Supply voltage range VP 3,6 to 18 V
  • Peak output current IOM max. 2,5 A
  • Output power at dtot= 10%
  • VP = 12 V; RL = 4 Ω Po typ. 4,2 W
  • VP = 9 V; RL = 4 Ω Po typ. 2,3 W
  • VP = 6 V; RL = 4 Ω Po typ. 1,0 W
  • Total harmonic distortion at Po = 1 W; RL = 4 Ω dtot typ. 0,3 %
  • Input impedance preamplifier (pin 8) |Zi | > 100 kΩ power amplifier (pin 6) |Zi| typ. 20 kΩ
  • Total quiescent current Itot typ. 14 mA
  • Operating ambient temperature Tamb −25 to + 150 °C
  • Storage temperature Tstg −55 to + 150 °C

LM378 dual4-watt amplifier Mini-stereo

Leave a Comment
This circuit is built around two chips: the MC1458 dual op amp, configured as a preamplifier, and the LM378 dual4-watt amplifier. The gain of the preamp is given by R3/R1 for one side and R4/R2 for the other side, which is about 100. That gain can be varied by increasing the ratios. The left and right channel inputs are applied to pins 2 and 6. The left and right outputs of U1 at pins 7 and 2 are coupled through CS/ RlO and C3/R6, respectively, to U2 to drive the two 8-0loudspeakers.
