ADL5310 is a low cost, dual logarithmic amplifier from Analog Devices that converts input current over a wide dynamic range to a linear-in-dB output voltage. It is optimized to determine the optical power in wide-ranging applications, such as gain and absorbance measurements.
The ADL5310 low‑cost dual logarithmic amplifier converts a wide‑range input current into a linear‑in‑dB voltage. It is optimized for optical power measurements in communication systems, laser control, and gain or attenuation monitoring. The device offers two independent channels, each with configurable slope and intercept, while sharing bias circuitry for low power consumption.
Key features include a 120 dB dynamic range, 24‑lead 4 mm × 4 mm LFCSP package, single‑ or dual‑supply operation, and user‑configurable output buffers. Detailed specifications cover input current range, logarithmic slope, temperature drift, supply limits, and pin functions.
