1 NC N/A 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 photocurrent 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 ) ≤ 11 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. 13–16 COMM Analog Ground.
