The ADL53101 low cost, dual logarithmic amplifier converts input current over a wide dynamic range to a linear-in-dB output voltage. It is optimized to determine the optical power in wideranging optical communication system applications, including control circuitry for lasers, optical switches, atten-uators, and amplifiers, as well as system monitoring. The device is equivalent to a dual AD8305 with enhanced dynamic range (120 dB). While the ADL5310 contains two independent signal channels with individually configurable transfer function constants (slope and intercept), internal bias circuitry is shared between channels for improved power consumption and channel matching. Dual converters in a single, compact LFCSP package yield spaceefficient solutions for measuring gain or attenuation across optical elements. Only a single supply is required; optional dual-supply operation offers added flexibility
