    • Evaluation Module for LOG114 Single-Supply, High-Speed, Precision Logarithmic Amplifier

    Overview

    The LOG114EVMLOG114EVM is a ready-to-use platform for evaluating the performance of the LOG114 in various configurations.The LOG114EVMLOG114EVM comes configured to operate on a single 5-V power supply. The circuit used in the LOG114EVMLOG114EVM 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.

    The LOG114 is a single-supply, high-speed, precision logarithmic amplifier. This device computes the logarithm or log-ratio of an input current or voltage relative to a reference current or voltage. The LOG114EVMLOG114EVM is a ready-to-use platform for evaluating the performance of the LOG114 in various configurations.
