7-Band, 2-Channel

Electronic Graphic Equalizer

Overview

Package Dimensions

The STK301-090 is an electronic graphic equalizer hybrid

IC that incorporates electronic volume control for 7-band,

2-channel equalization for one-touch up/down control of

all band gains. Further, low-profile packaging is realized

using Sanyo’s insulated metal substrate technology

(IMST) for the base, SC system and photoresist technolo-

gies and folded board construction.

Applications

• Car stereos

• Radio cassette recorders

• Home stereos

Features

• Gain adjustable in ±2dB steps in all bands

• 13-position control with +12dB maximum boost and

−12dB maximum cut in all bands

• Band center frequencies (fO): 60Hz, 150Hz, 400Hz,

1kHz, 2.5kHz, 6kHz, 15kHz

• A graphic equalization system can be constructed using

3 ICs—the STK301-090, a controller (general-purpose

microcontroller) and a display LSI (LC75821 for LCDs;

LC7565 for FLT/LEDs)—with the following features.

- One-touch up/down gain control in all bands

- One-touch memory recall of preset band settings for

tailored frequency response for individual musical

tastes.

- One-touch gain reset to 0dB (flat response function)

and gain boost/cut reverse around 0dB center (reverse

response function) under supported software control

- 2 control lines which can also be used to interface

with the display LSI for easy connection between the

display LSI and the microcontroller

• Low boost and cut operating shock noise
