M61530FP
4ch Electronic Volume with 5.1ch Analog Input
REJ03F0058-0100Z
Rev.1.0
Sep.19.2003
Description
The M61530FP is a four-channel volume IC which is optimal for combination with the M61519FP two-channel
electronic volume. A multi-channel system is easily configured with the aid of these two chips.
Features
Function names
Main volume control
Low pass filter (LPF)
AGC
Bass boost
Output gain control
Input gain control
Microcomputer I/F
Features
0 to 87 dB in 1-dB steps, −∞
Four independently controlled volumes (SL, SR, C, LFE)
On-chip operational amplifiers for configuration of post-filters through the addition of external C
and R elements
AGC circuit is included to prevent clipping <SW ch>
HPF type, with on/off switch <SL/SR ch>
0, +6, +9, or +12 dB (four steps) <SW ch>
0, +5, +10 dB (three steps) <FL/FR ch>
Two-line serial data control
Application
Mini-component systems, micro-component systems, etc.
