Figure 1. PGA4311 Block Diagram.
If during normal operation the power supply voltage
drops below
±
3.2V, the circuit enters a hardware MUTE
state. A power-up sequence will be initiated if the
power-supply voltage returns to greater than
±
3.2V.
ANALOG INPUTS AND OUTPUTS
The PGA4311 includes four independent channels.
Each channel has a corresponding input and output pin.
The input and output pins are unbalanced, and refer-
enced to analog ground.
The input and output pins may swing within 1.25V of the
analog power supplies, V
A
+ and V
A
–
. Given V
A
+ = +5V
and V
A
–
=
–
5V, the maximum input or output voltage
range is 7.5Vp-p.
For optimal performance, it is best to drive the PGA4311
with a low source impedance. A source impedance of
600
or less is recommended. Source impedances up
to 2k
will cause minimal degradation of THD+N. Please
refer to the
“
THD+N vs Source Impedance
”
plot in the
Typical Characteristics section of the datasheet.
