Function

Description

Interface Schematic

ISET

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 -0.7 V),

all circuits are operating; when logic “low” (

≤0.5V), all circuits are

turned off. The input impedance of this pin is >10k

Ω. A DC voltage less

than or equal to the maximum allowable VCC may be applied to this pin

when no voltage is applied to the VCC pins.

Pkg

Base

GND

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.
