3-element 2-ch Graphic Equalizer IC
REJ03F0082-0100Z Rev.1.0 Sep.22.2003
Description
This 2-ch, 3-element graphic equalizer IC is ideal for Hi-Fi audio devices, and features three transistor-type resonance circuits and an output operating amp that handles two channels built into it. It is designed for use in radio cassette players, car stereos, portable stereos and other devices.
Features
* Two-channel (stereo) processing is possible with single IC. * An internal reference voltage circuit eliminates the need for a large-volume capacitor and makes it possible to use fewer components. * The Gv can be varied using an external resistor. * Low noise ........................... VNO FLAT = 4 Vrms (standard) * Low distortion .................... THD = 0.004% (standard) (@f = 1 kHz, FLAT)
