Product Details
●The AD8015 is a wide bandwidth, single supply transimpedance amplifier optimized for use in a fiber optic receiver circuit. It is a complete, single chip solution for converting photodiode current into a differential voltage output. The 240 MHz bandwidth enables AD8015 application in FDDI receivers and SONET/SDH receivers with data rates up to 155 Mbps. This high bandwidth supports data rates beyond 300 Mbps. The differential outputs drive ECL directly, or can drive a comparator/ fiber optic post amplifier.
●In addition to fiber optic applications, this low cost, silicon alternative to GaAs-based transimpedance amplifiers is ideal for systems requiring a wide dynamic range preamplifier or single-ended to differential conversion. The IC can be used with a standard ECL power supply (-5.2 V) or a PECL (+5 V) power supply; the common mode at the output is ECL compatible. The AD8015 is available in die form, or in an 8-pin SOIC package.
