Description
1
GAIN
Gain Control.
2
DETO
Detector Output. Provides an output error current for the AGC function.
3
HPFL
High-Pass Filter Connection. A capacitor to ground sets the corner frequency of the internal output offset
control loop that controls the minimum usable input frequency.
4, 14, 15
DECL
Decoupling Pin. Nominally ~VS/2. Decoupling capacitance may need to be adjusted for AGC operation
(see the Applications Information section).
5
DETI
Detector Input. DC level referenced to DECL pin.
6, 7
OCOM
Connect OCOM to low impedance ground.
8
OUTP
Signal Output. Must be ac-coupled.
9, 10
VPSO
Positive Supply Voltage, 4.5 V to 5.5 V. VPSO and VPSI must be connected together externally and
properly bypassed.
11, 12, 13, 22, 23
VPSI
Positive Supply Voltage, 4.5 V to 5.5 V. VPSO and VPSI must be connected together externally and
properly bypassed.
16, 17, 18, 20
ICOM
Connect ICOM to low impedance ground.
19
INPT
Signal Input. Must be ac-coupled.
21
MODE
Gain Direction Control. High for positive slope. Low for negative slope.
24
ENBL
Apply a Positive Voltage (2.5 V
≤ V
ENBL
≤ VPSI) to Activate Device.
EPAD
Exposed Pad. Connect the exposed pad to low impedance ground.
