4. Single-end usage
The load impedance for the output pin should be higher than 5k
. When the AK4319A drives some capacitive
load, series resistor(220ohm or more than) should be added the analog output and it should be connected to
the analog output pin as near as possible. The output pin which is not used could be left open. When the
AK4319A is used as a single-end configuration, the analog characteristics (such as THD+N, DR, S/N) may
degrade by 1dB.
For single-end operation, in the circuit example of
Figure 9 ,
DC isolation capacitance is added between
AOUT- and 10k
. Then the 10k
resistor which is connected to AOUT+ is removed. In this case, the output
level becomes 0.99Vrms. With a single-end configuration, the AK4319A interfaces directly to external circuit
such as volume AMP which simplifies the circuit.
Figure 10 shows a circuit example for single end operation. The series resistor should be connected to
the AOUT pin as near as possible. The operation mode setting in this circuit is as follows.
[Operation mode]
fs=44.1kHz
De-emphasis ON/OFF for fs=44.1kHz
Data format: Mode 0, 16bit LSB justified
BICK: 64fs
MCLK: 256fs
[Performancet example]
THD+N: -86dB
DR,S/N: 91dB
