TIPD186 Reference Design

Texas Instruments

Tone Stack for Guitar Amplifier Reference Design

Description

This split-supply: high-performance guitar tone circuit provides control of the bass: mid: and treble frequencies of an electric guitar signal: while also providing gain with minimal distortion and noise. Buffered inputs and outputs preserve the behavior of the system independent of the source and load impedances: and a radio frequency (RF) filter on the circuit front end attenuates noise from outside the audio band.

Features
  • THD+N at 1 kHz: -105 dBTreble adjustment range: 10 dBMid adjustment range: 9 dBBass adjustment range: 19 dBSupply voltage: ±15 VUtilizies OPA1642 high-performance: JFET-input audio operational amplifier
Applications
  • Guitar amplifier & other music instrument amplifier
