Description
M61529FP is the semiconductor integrated circuit for Home Audio. M61529FP includes 2ch electronic volume,
Tone control, 4 Input Selector, Bass Boost, REC output and Mic Mixing. This IC is suitable for Mini Component.
A difference in M61529FP and M61519FP has just changed Tone Input ATT from 0/–13dB to 0/–8.2dB.
Features
• 2ch Master Volume (L,R Independent Control)
Main Volume : 0dB to –76dB (2dB or 4dB step), –∞
Trim Volume : 0dB to –15dB (1dB step)
*Total level is fixed at –87dB, on condition that the total level of Trim and Master volume is under “–87dB”.
• Tone Control (Bass/Mid/Treble)
±8dB (2dB step)
• 4 Input Selector with Mute
• Surround Function
• Vocal Cut Function
• Bass Boost Function
• L+R Output for Spectrum Analysis Display
• L+R Output for Subwoofer
• MIC Mixing Function
• 2 REC output with mute
• Input ATT
: –5/0/+3.5dB
• Tone Input ATT
: 0/–8.2dB
• External Input ATT
: +3/0/–3/–6dB
Application
Mini/Micro Component, Radio-Cassette Recorder with CD Player, etc.
Recommended Operating Conditions
Supply voltage range……………………8.0 to 10.0V
Recommended supply voltage……………...…...9.0V

System Reset
(a) IC’s condition of power supply turn on
This IC is the system composition which compulsory resetting when power supply turn on.
• Time constant of power supply is used, and reset pulse is formed.
• When VCC exceed 5.5V, reset pulse is transmitted. (Logic circuit ON) [1]
• The operation time of reset is released reset pulse [2] from transmitted reset pulse [1].
• Trst = [Timing A + about 20us] is time of released reset pulse.
(Timing A is time of VCC exceed 5.5V.)

The power supply is turned on, and resetting is released after Trst, and the reception of the serial
data becomes possible in Logic block.
However, REF voltage doesn't operate in less than 1.5V in the analog block. Make REF voltage is to
transmit serial data by more than 1.5V.
• REF Voltage ≥ Time of REF=1.5V =Timing B
(Timing B is time when analog block operates and to become possible.)
<EX> Capacitor of 1pin =100µF
Becomes REF ≥ 1.5V in about 200ms.
(b) IC’s condition of power supply turn off
Internal power supply (VDD, VSS) decreases to VCC together, too.
All the data set up when Logic turned it off become invalid.
