A 7-point stereo graphic equalizer display filter IC
San L. Lin, C.W. Solomon · IEEE Transactions on Consumer Electronics · 1990
A seven-point graphic equalizer display filter IC for use in audio applications is described. The device is implemented in a three-micron CMOS process, and utilizes switched capacitor circuit technology to replace several discrete components (opamps, diodes, resistors, capacitors) which occupy significant board space. The chip occupies 17000 square mils and dissipates about 120 mW. Typical performance measurements of the device are given.>
