M61530FP Datasheet | Renesas

Description The M61530FP is a four-channel volume IC which is optimal for bination 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 Microputer I/F Features 0 to - 87 d B in 1-d B 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 d B (four steps) <SW ch> 0, +5, +10 d B (three steps) <FL/FR ch> Two-line serial data control Application Mini-ponent systems, micro-ponent systems, etc. Remended Operating Conditions Power-supply voltage range: Vcc = 8 to 10 V Rated power-supply voltage: Vcc = 9 V Rev.1.0, Sep.19.2003, page 1 of 18 ..
