Relationship Between Amplifier Bandwidth Slew-Rate Requirements, and Phase Distortion

Document Thumbnail

A rational basis is presented for the maximum bandwidth and maximum slew rate required in audio amplifiers. The bandwidth requirements are obtained by examining the phase and differential time delay distortions after the group or signal delay has been accounted for. The slew-rate requirements are obtained by examining the worst case signal conditions for a given bandwidthand power output. It is shown that a high-pass filter with a cutoff frequency in the signal bandwidth can reduce the amplifier overload margin by a factor of two.
