Five Band Graphic Equalizer Data Sheet Multiplexor Operation The DC peak output for measurement is se- lected using the reset and strobe pins. Reset high resets the multiplexor. Reset low enables the strobe pin. After the first strobe leading edge, 100Hz output is on OUT. Each additional strobe leading edge advances the multiplexor one channel (100Hz, 330Hz, 1kHz, 3.3kHz, 10kHz, etc.) and this will repeat indefinitely. The multiplexor read rate is also the output de- cay time control. Each read decays that chan- nel approximately 10%.
