Description
1
INM
Signal Input Minus Polarity. Normally at VPOS/2.
2
COM
Common Pin (Usually Grounded).
3
OFS
Offset Adjustment. External capacitor connection.
4
OUT
Logarithmic (RSSI) Output Voltage. ROUT = 12.5 kΩ.
5
INT
Intercept Adjustment, ±3 dB. (See the Slope and Intercept Adjustments section.)
6
ENB
CMOS-Compatible Chip Enable. Active when high.
7
VPS
Positive Supply: 2.7 V to 5.5 V.
8
INP
Signal Input Plus Polarity. Normally at VPOS/2. Due to the symmetrical nature of the response, there is no special
significance to the sign of the two input pins. DC resistance from INP to INM = 1.1 kΩ.
