Overview: Ordering number : EN4793A Thick-Film Hybrid IC STK301-220
7-band, 2-channel Electronic Graphic Equalizer Overview
The STK301-220 is a hybrid IC (HIC) for electronically controlled graphic equalizer applications and is equipped with on-chip electronic volume control for 7-band, 2channel graphic equalization, thereby permitting onetouch up-down control of all band gains. The STK301220 is a hybrid IC which combines SC system and photoresist techniques with folded board construction while incorporating Sanyo’s unique insulated metal substrate technology (IMST) to the base. Applications
• Car stereos • Portable radio-cassette players • Home stereos — One-touch up-down control of all band gains. — Immediate recall of preferred frequency levels tailored to suit musical selections. This is possible using preset functions to retrieving items from one-touch memory. — Such functions as setting all bands to 0 dB (flat function), or switching frequency characteristics from 0 dB to center (reverse function) may be simply performed with supported software. — Dual control lines permit mutual use with display LSI and help to simplify wiring between microcontroller and LSI. • Minimal operating shock noise when boost or cut is used.
