Transimpedance Logarithmic Amplifier

Home / Transimpedance Logarithmic Amplifier

The device computes the logarithm or log-ratio of an input current or voltage relative to a reference current or voltage (logarithmic transimpedance amplifier). High precision is verified over a wide dynamic range of input signals on either bipolar (±5V) or single (5V) supply. The amplifier was used both to measure pixel currents in an imager as well as currents from a floating gate array for accurate programming. The OPA380 far exceeds the offset, drift, and noise performance that conventional JFET op amps provide.
