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.","metaTitle":"LOG114AIRGVT Logarithmic Amplifier, 5 MHz Bandwidth, 16-VQFN","metaDescription":"Texas Instruments LOG114AIRGVT logarithmic amplifier IC, 5 MHz -3dB bandwidth, 5V/µs slew rate, 100 µV offset, 5 pA bias.
