Description

This TI Verified Design implements an analog active crossover solution for two-way loudspeakers which is suitable for recording studios or home high-fidelity systems. The woofer signal pathway includes a low-pass shelving circuit for baffle step compensation and a 4th-order Linkwitz-Riley low-pass filter. The tweeter signal pathway includes a 4th-order Linkwitz-Riley high-pass filter, 3rd-order all-pass filter for time alignment, and output attenuation and buffering.

Features
  • Implements a 4th-order Linkwitz-Riley crossover for two-way loudspeakers
  • Professional audio levels (+4dBu/1.228Vrms)
  • Low-pass shelving circuit for baffle step compensation
  • 3rd-order all pass filter for time alignment
  • Utilizes OPA1602/1604 low noise operational amplifiers
