Click and Pop TDA2050 32W Amp
I've implemented a circuit using the TDA2050 Amplifier. I am using split supply (+5v/-5v). I hear a click when i unmute the input and a pop when i mute the input to the amplifier. The input is given through a PGA2311 (Programmable Gain Amplifier) which has a MUTE pin which i am using to MUTE/UNMUTE the input to the amplifier.
I am using the reference circuit in the datasheet attached. The input is a pure sine wave at frequency 1KHz. |
