5-channel graphic equalizer

BA3812L

The BA3812L is a five-point graphic equalizer that has all the required functions integrated onto one IC. The IC is com-

prised 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 applica-

tions. 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.

FApplications

Radio cassette players, home stereo systems and car stereo systems.

FFeatures

1) Minimizes the number of components required to

build a graphic equalizer.

4) Low current dissipation (5 mA).

5) Wide dynamic range (V^OM= 2.1Vrms /VCC = 8V).

6) Built-in input and output buffer amplifiers.

2) Low distortion and low noise.

3) Wide operating power supply voltage range (3.5V to

16V).

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
