Pin No. Mnemonic 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 ~V
S
/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.
