The average power and extinction ratio can be set with a voltage provided by a microcontroller DAC or by a trimmable resistor. The part provides both bias and modulation currentmonitoring, as well as fail alarms and automatic laser shutdown.The ADN2872, a SFF-/SFP-compliant laser diode driver, canwork with the Analog Devices, Inc., ADuC7019/ADuC702xMicroConverter® family and the ADN289x limiting amplifierfamily, to form a complete SFP/SFF transceiver solution. The ADN2872 is available in a space-saving 4 mm × 4 mm LFCSPspecified over the −40°C to +85°C temperature range.
