AD8015 is a low cost, wide bandwidth, low noise transimpedance amplifier with 240 MHz bandwidth and 3.0 pA/√Hz input current noise. It is suitable for high bandwidth, low noise fiber optic receivers.
The AD8015 is a 240 MHz bandwidth, low‑noise, single‑supply transimpedance amplifier optimized for fiber‑optic receiver circuits. It converts photodiode current to a differential voltage, offering both single‑ended and differential output configurations and supporting operation from +4.5 V to +11 V.
Typical applications include SONET/SDH and FDDI fiber‑optic receivers, low‑noise preamplifiers, and single‑ended‑to‑differential conversion. The device features low input current noise (3 pA/√Hz at 100 MHz), a total RMS input noise of 26.5 nA up to 100 MHz, and an optical sensitivity of –36 dBm at 155 Mbps.
