Description
Signal Common. Connect to low impedance ground.
A HI Activates the Device.
Signal Input. 200 Ω to ground.
Gain Direction Control. HI for positive slope; LO for negative slope.
Gain Control Voltage Input.
Detector Output. Provides output current for RSSI function and AGC control.
Power Common. Connect to low impedance ground.
Output Centering Loop Decoupling Pin.
Signal Output. To be externally ac-coupled to load.
Positive Supply Voltage. 2.7 V to 5.5 V. VPSI and VPSO are tied together internally with back-to-back
PN junctions. They should be tied together externally and properly bypassed.
Positive Supply Voltage. 2.7 V to 5.5 V.
High-Pass Filter Connection. A capacitor to ground sets the corner frequency of the output offset control loop.
