NJU7305

The NJU7305 is a electrical variable resistor (EVR) incorporated 7-band each for left and right channels, especially apply to stereo type graphic equalizer. This device consists of input controller, channel / band / level selector, 14 latches and resistor network blocks of 7 bands each for left and right channels. The boost and cut value for each band of each channel can be set independently to each other by the channel / band / level selector controlled y external controller. The maximum boost and cut range is +/-12 dB and the boost and cut value is adjusted by +/-2 dB step.

Features of the NJU7305 are:(1)7 bands each for left and right channels;(2)stereo application graphic equalizer: each channel independent operation;(3)maximum boost and cut: +/-12 dB;(4)boost and cut step: +/-2 dB;(5)8-bit serial data for the equalizing;(6)flat level setting function;(7)operating voltage: 7.5 to 15 V;(8)package outline: SDMP 30 / SDIP 28;(9)CMOS technology.

The absolute maximum ratings of the NJU7305 can be summarized as:(1)supply voltage VDD-VEE: 16 V;(2)supply voltage Vcc: Vss to Vss+7 V;(3)input voltage: Vss-0.3 to Vcc+0.3 V;(4)input voltage: VEE-0.3 to VDD+0.3 V;(5)power dissipation: 200 mW;(6)operating temperature: -20 to +75;(7)storage temperature: -40 to +125.
