ADL5310ACPZ-REEL7

The ADL5310ACPZ-REEL7 is a 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 wide-ranging optical communication system applications, including control circuitry for lasers, optical switches, attenuators and amplifiers, as well as system monitoring. The device is equivalent to a dual AD8305 with enhanced dynamic range (120dB). 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 space-efficient solutions for measuring gain or attenuation across optical elements.
