Analog, Active Crossover Circuit for Two-Way Loudspeakers
TIPD134
Overview
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
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
