APPLICATION INFORMATION
Following general recommendations apply for MAS6116 applications.
1) All four ground pins LGND, RGND, AGND and DGND have to have low ohmic connection to the same
physical ground net. Any potential difference between these ground nets may potentially trigger destructive
latch-up phenomena.
2) Keep audio input signals off until the MAS6116 has proper supply voltages.
3) In power up provide +5V supply voltage for the MAS6116 before supplying power to the external operational
amplifiers. In power down turn off powers in reverse order i.e. turn off last +5V supply voltage. This power up
/ down procedure guarantees that MAS6116 provides always proper feedback loop for the operational
amplifier circuit signals.
4) The LMO and RMO virtual ground pin voltages should be kept within ±100mV from ground potential. To
guarantee this it is possible to add external Shottky diodes in both directions from LMO and RMO to ground.
