Multimedia ICs Vocal fader IC BA3837 / BA3837F / BA3838F The BA3837, BA3837F and BA3838F are ICs with an internal secondary active LPF for vocal cancellation functions and mixing amplifier functions with high degrees of vocal cancellation. Three control pins are used to switch between modes: the key controller input mode, through mode, vocal fader mode, sound multiplexing mode and mute mode. By offering these functions on a single chip, these ICs can significantly reduce the number of external components. Applications • Karaoke functions on stereo systems, portable stereos and VCRs Features • 1) Single-chip IC with vocal fader, to erase vocals from commercially available recordings. 2) Internal secondary active LPF for high degrees of vocal cancellation (high synchronization rejection). 3) Three control pins for switching between 4 modes: through, vocal fader, sound multiplexing and mute. 4) Key controller input and internal switches. 5) Low noise and low distortion. 6) Internal [ … ]
