TIPD136, Active Volume Control for Professional Audio

TIPD136, Active Volume Control for Professional Audio. This Verified Design implements a split-supply, high-performance volume control which attenuates a professional line-level audio signal with minimal distortion and noise. An input buffer preserves the behavior of the system independent of the audio input source impedance. A radio frequency (RF) filter on the circuit front end removes noise from outside the audio band, while a bidirectional transient voltage suppressor (TVS) diode protects against overvoltage spikes
