ADL5308-EVALZ

ADL5308-EVALZ is an evaluation board allows evaluation of the ADL5308 fast response 188dB range (10pA to 25mA) logarithmic converter IC. The ADL5308 is a monolithic logarithmic transimpedance amplifier, optimized for measurement of low frequency, and wide dynamic range signal power in fibre optic systems. It produces an output voltage proportional to the logarithm of the ratio between the input current at pin INP, and an internal reference current. The reference current can also be supplied externally through the IREF interface. 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.

• Full-featured evaluation board for the ADL5308
• Supports external electrical input or on-board photodiode (PD) for optical input
• On-chip or external PD bias (PDB)
• Comparator reference and output connectors with adjustable hysteresis
