Product details

Logarithmic amplifier for wide-dynamic-range signal conditioning

The LOG114AIRGVT: It converts input currents or voltages over multiple decades into a linearized output voltage, making it the natural choice for photodiode front-ends, optical power monitoring, and any application where the signal spans a wide dynamic range. The -3 dB bandwidth is 5 MHz and the slew rate is 5 V/µs, so it handles modulated optical signals up into the low-MHz region without losing the log conformance. Input bias current is 5 pA, which keeps the error negligible when working with photodiode currents in the nanoamp range.

Supply range, offset, and output drive

The LOG114AIRGVT operates from a single supply spanning 4.8 V to 11 V. Input offset voltage is 100 µV. Supply current is 10 mA.

Temperature range — indoor and controlled environments

The operating temperature range is -5°C to 75°C.

Active lifecycle and compliance

ROHS3 compliant.

Frequently asked questions

What is LOG114AIRGVT used for?

It is a logarithmic amplifier used in photodiode signal conditioning, optical power measurement, wide-dynamic-range current-to-voltage conversion, and any application that requires compressing a multi-decade input range into a linear output voltage.

Is LOG114AIRGVT RoHS compliant?

Yes, it is ROHS3 compliant.

Is LOG114AIRGVT compatible with 3.3V logic?

The supply range is 4.8 V to 11 V, so it cannot run from a 3.3 V rail. If the ADC or controller uses 3.3 V logic, the output will need level translation or the supply must be at least 4.8 V.
