Analog Devices Inc. ADL5308 Evaluation Board & Kit

Analog Devices ADL5308 Evaluation Board and Kit is configured to evaluate the operation of the ADL5308 logarithmic converter IC. The ADL5308 is a monolithic logarithmic transimpedance amplifier optimized for measuring low frequency and wide dynamic range signal power in fiber optic systems. The logarithmic slope and intercept are both factory-trimmed to a nominal value of 200mV/dec and 10pA, respectively. Both can be adjusted through the I²C interface. The ADI ADL5308 evaluation board offers a comparator reference and output connectors with adjustable hysteresis.
