five-point graphic equalizer
Courtesy/Thanks to: Rohm
Description: The BA3812L is a five-point graphic equalizer that has all the required functions integrated onto one IC. The IC is comprised
of the five tone control circuits and input and output buffer amplifiers.
The BA3812L features low distortion, low noise, and wide dynamic range, and is an ideal choice for Hi-Fi stereo applications.
It also has a wide operating voltage range (3.5V to 16V), which means that it can be adapted for use with most
types of stereo equipment.
The five center frequencies are independently set using external capacitors, and as the output stage buffer amplifier and
tone control section are independent circuits, fine control over a part of the frequency bandwidth is possible, By using
two BA3812Ls, it is possible to construct a 10-point graphic equalizer.
The amount of boost and cut can be set by external components.
