Circuit type
LC7527E
Power supply: Analog ground
The impedance of the pattern connected to these pins should
be kept as low as possible.
LVref and RVref are not connected to the V
Left channel audio signal input
IN1 is normally connected to an operational amplifier inverting
input.
IN2 is normally connected to an operational amplifier non-
inverting input.
Right channel audio signal input
IN1 is normally connected to an operational amplifier inverting
input.
IN2 is normally connected to an operational amplifier non-
inverting input.
Chip enable input. Internal data is latched when this pin goes
from high to low and the analog switches operate. Data
transfers are enabled when this pin is high.
Clock input. Schmitt inverter input circuit
