The MAX3260 high-speed transimpedance amplifier is ideally suited for Fibre Channel and SDH/SONET applications. It features a 1GHz bandwidth, single 5V supply, and a maximum input current of 900μA with a dynamic range of 25dB.
The MAX3260 is a high‑speed transimpedance amplifier designed for Fibre Channel and SDH/SONET applications. It offers a 1 GHz bandwidth, single 5 V supply operation, and a 25 dB dynamic range, making it suitable for optical receiver systems that require input currents up to 900 µA.
The datasheet provides absolute maximum ratings, detailed electrical characteristics, typical operating curves, and design recommendations such as proper layout, termination, and filter usage to minimize noise and power consumption. Power draw is about 115 mW when AC‑coupled and can be reduced by adjusting termination resistance.
| Bandwidth | 1 GHz |
|---|---|
| Supply Voltage | 5 V (single) |
| Dynamic Range | 25 dB |
| Peak Input Current | 900 µA |
| Power Consumption (AC‑coupled) | 115 mW |
The input bias voltage (VIN) is typically 1.6 V.
The device provides a 1 GHz bandwidth.
A 50 Ω termination to ground is typical; using a 75 Ω termination reduces standing current to about 22 mA.
