1.3 Specification

The LOG200EVM offers the following features:

  • The evaluation board enables users to connect the LOG200 to current sources through SMA connections via series resistors.

  • The PCB includes a footprint to mount an optional photodiode to the INUM input for optical power measurement applications. The photosensor can be biased externally through a test point, or through the use of the LOG200 IBIAS adaptive biasing current output function by modifying the EVM.

  • Allows access to the integrated precision 1 µA current reference

  • Allows the use of the Integrated precision 1.65 V and 2.5 V voltage references in different circuit configurations

  • The LOG200EVM provides access to the inputs and output of the secondary op-amp. The PCB provides optional passive component footprints to support different op-amp or filter configurations.
