LC75366M

Ordering number : EN4929A CMOS LSI LC75366, 75366M Two-Channel Electronic Volume Control Overview The LC75366 (DIP20) and the LC75366M (MFP20) are electronic volume controls that can be controlled by serial input data and provide volume, balance and loudness functions. Package Dimensions unit: mm 3021B-DIP20 [LC75366] Features Silicon gate CMOS process for low switching noise Functions Volume: 0 dB to –68 dB (in 2 dB steps) and – ∞ ; 36 positions. A balance function can be implemented by controlling the left and right channel volume settings independently. Loudness: Taps are provided at the –20 dB positions in the 10 dB step resistor ladder used by the volume control function. A loudness function can be implemented by attaching external RC circuits at these tap points. An address selection pin (the S pin) allows two LC75366 chips to be used on the same bus. Serial data input: Supports CCB* format communication with the system controller. SANYO: DIP20 unit: mm 3036B-MFP20 [LC75366M] CCB is a trademark of SANYO ELECTRIC CO., LTD. CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
