Connecting to the LOG114EVM
The LOG114 requires only a few connections to operate: a 5-V power supply, an input source such as a
photodiode or resistor, and a digital voltmeter or oscilloscope.

Electrostatic Discharge Warning
CAUTION
Many of the components on the LOG114EVM are susceptible to damage by
electrostatic discharge (ESD). Customers are advised to observe proper ESD
handling precautions when unpacking and handling the EVM, including the use
of a grounded wrist strap at an approved ESD workstation.

Using a Photodiode
An anode of a photodiode can be connected to the LOG114 by either using the pads or pin sockets on the
LOG114EVM. To use the high-current linearity correction circuitry, connect the photodiode as illustrated in
LOG114EVM. To use the high-current linearity correction circuitry, connect the photodiode as illustrated in
