NAME
FUNCTION
1, 9
N.C.
No Connection. Not internally connected.
2
REFVOUT
1.238V Reference Voltage Output. Bypass REFVOUT to GND with a 0 to 1F capacitor (optional).
3
GND
Ground
4VEE
Negative Power Supply. Bypass VEE to GND with a 0.1F capacitor.
5
LOGV1
Logarithmic Amplifier Voltage Output 1. The output scale factor of LOGV1 is -0.25V/decade.
6
OSADJ
Offset Adjust Input. Apply a voltage at OSADJ to adjust the LOGV2 output offset voltage
(see the Output Offset section).
7
SCALE
Scale Factor Input. Adjust the output scale factor for LOGV2 using a resistive divider (see the Scale
Factor section).
8
LOGV2
Logarithmic Amplifier Voltage Output 2. Adjust the output scale factor for LOGV2 using a resistive
divider between SCALE, GND, and LOGV2 (see the Scale Factor section).
10
VCC
Positive Power Supply. Bypass VCC to GND with a 0.1F capacitor.
11
REFISET
Current Reference Adjust Input. A resistor (RSET), from REFISET to GND, adjusts the current at
REFIOUT (see the Adjusting the Logarithmic Intercept section).
12
CMVOUT
0V Common-Mode Voltage Reference Output
13
REFIOUT
Current Reference Output. The internal current reference output is available at REFIOUT.
14
REFIIN
Current Reference Input. Apply an external reference current at REFIIN. IREFIIN is the reference
current used by the logarithmic amplifier when generating LOGV1.
15
LOGIIN
Current Input to Logarithmic Amplifier. LOGIIN is typically connected to a photodiode anode or other
external current source.
16
CMVIN
Common-Mode Voltage Input. VCMVIN is the common-mode voltage for the input and reference
amplifiers (see the Common Mode section).
