The LOG114EVM is a ready-to-use platform for evaluating the performance of the LOG114 in various configurations.The LOG114EVM comes configured to operate on a single 5-V power supply. The circuit used in the LOG114EVM is designed to operate over a wide range of input currents (10 nA to 10 mA) and scales the output voltage from 1.15 V to 2.75 V. Additional circuitry includes a precision level shifter and high-current linearity correction section.
