LC75392M Datasheet Single-Chip Electronic Volume Control

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : EN5681 CMOS LSI LC75392, 75392M Single-Chip Electronic Volume Control System Overview The LC75392 (DIP-30SD) and the LC75392M (MFP30S) are electronic volume control ICs that provide input and output switching, volume, and tone control functions controlled by data transferred over a serial interface. Package Dimensions unit: mm 3196-DIP30SD [LC75392] Functions • Input and output switching: Four inputs and outputs can be switched independently. • Volume control: A balance function can be implemented by controlling the left and right levels independently. Each channel can be set to 0 to –20 dB in 2 dB steps, –20 to –32 dB in 3 dB steps, –32 to –52 dB in 4 dB steps, –52 dB to –70 dB in 4.5 dB steps, and –∞. •Tone controls: Internal switches are provided to select between four sets of frequency characteristics. A buffer function can be implemented using external components.
