APPLICATION INFORMATION
audio-distribution amplifier
This audio-distribution amplifier (see Figure 69) feeds the input signal to three separate output channels. U1A
amplifies the input signal with a gain of 10, while U1B, U1C, and U1D serve as buffers to the output channels.
The gain response of this circuit is very flat from 20 Hz to 20 kHz. The TL03x allows quick response to the input
signal while maintaining low power consumption.
