Description
Connected to ground through an external resistor. The value can be
varied to change the current in the AGC for optimum linearity and cur-
rent consumption.
Power down control for overall circuit. When logic “high” (
≥
V
CC
-0.7V),
all circuits are operating; when logic “l(fā)ow” (
≤
0.5V), all circuits are
turned off. The input impedance of this pin is >10k
. A DC voltage less
than or equal to the maximum allowable V
CC
may be applied to this pin
when no voltage is applied to the V
CC
pins.
Ground connection. The backside of the package should be soldered to
a top side ground pad which is connected to the ground plane with mul-
tiple vias.
