Assignment
Must be connected bypass capacitor (e.g. 1 500 pF) to minimize
ground impedance.
Must be connected to the system ground with minimum inductance.
Ground pattern on the board should be formed as wide as possible.
(Track length should be kept as short as possible)
Must be coupled with capacitor (e.g. 1 500 pF) for DC cut.
Supply voltage 5.0
capacitor (e.g. 1 500 pF) to minimize ground impedance.
Can be used for auto gain control. The control can be governed by
supply voltage to this pin. AGC performance can be adjustable by
