Serial Interface Timing
APPLICATION INFORMATION
Power supply connection and decoupling
To get the best performance of the chip all digital
activities should be avoided during analog signal
processing.
Important: Analog (AVDD) and digital (DVDD)
supply voltage pins should be always connected
directly together to keep them in the same voltage
potential. No resistor is allowed in connection
between AVDD and DVDD (see supply voltage
connection circuit in the Application Note 1 on the
next page). Otherwise possible voltage difference
Opamp produced output offset voltage
Opamp non-idealities in input offset voltage and in
input bias current both produce offset voltage to the
output. Since this offset voltage is gain dependent
the gain change step can produce dc voltage steps
to
performance it is recommended to use opamps
which have both low input offset voltage and low

could trigger latch-up phenomenom which can
damage the device. Due to the same reason also
the digital control input voltages should not exceed
supply and ground voltages as specified in absolute
maximum rating specifications on page 6. These
requirements are valid also during the startup when
supply voltages are applied.
Low noise supply voltages should be used for high
quality audio. Supply decoupling capacitors must be
located as close to MAS9116 as possible.

OP277 has excellent offset and bias and no
trimming is needed. Also Analog Devices OP1177
and AD8610 offer very good offset performance.
See table below for these and other recommended
op-amps.
