LOG114AIRGVT, Logarithmic Amplifiers Precision High-Speed

Semiconductors\Integrated Circuits - ICs\Amplifier ICs\Logarithmic AmplifiersLOG114 Precision Logarithmic Amplifier Texas Instruments LOG114 Precision Logarithmic Amplifier is designed for measuring low-level and wide dynamic range currents in communications, lasers, medical, and industrial systems. TI LOG114 Logarithmic Amplifier 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 ensured over a wide dynamic range of input signals on either bipolar (±5V) or single (+5V) supply. Special temperature drift compensation circuitry is included on-chip. In log-ratio applications, the signal current may be from a high impedance source such as a photodiode or resistor in series with a low impedance voltage source. The reference current is provided by a resistor in series with a precision internal voltage reference, photo diode, or active current source. LOG114EVM is a ready-to-use platform for evaluating the performance of the LOG114 in various configurations.
