Function
1
VRDZ
Top of a Resistive Divider Network that Offsets VLOG to Position the Intercept. Normally connected to VREF;
may also be connected to ground when bipolar outputs are to be provided.
2
VREF
Reference Output Voltage of 2.5 V.
3
IREF
Accepts (Sinks) Reference Current, IREF.
4
INPT
Accepts (Sinks) Photodiode Current, IPD. Usually connected to photodiode anode such that photo current
flows into INPT.
5
VSUM
Guard Pin. Used to shield the INPT current line and for optional adjustment of the INPT and IREF node
potential.
6, 7
VNEG
Optional Negative Supply, VN (this pin is usually grounded; for details of usage, see the Applications section.
8
VPOS
Positive Supply, (VP VN ) ≤ 12 V.
9
VLOG
Output of the Logarithmic Front End.
10
BFIN
Buffer Amplifier Noninverting Input.
11
SCAL
Buffer Amplifier Inverting Input.
12
VOUT
Buffer Output.
13 to 16
COMM
Analog Ground.
EPAD
The exposed pad must be soldered to ground.
