ADN8810:  A Programmable Precision Current Source Designed For Tunable Lasers

Product Details


The ADN8810 is a programmable precision current source designed for tunable lasers. It features a precision 12-bit DAC and precision V/A converter built in along with a high precision current output. Its max output current can be scaled from 50 mA to 300 mA by external sense resistors value.

The ADN8810 provides high precision, low noise current sources and all other control signals needed for tunable laser devices. It can drive the Laser section, the Laser Front Mirror, Back Mirror, Phase, Gain or amplification while interfacing to the host system over a serial interface. The host controls the operation of the controller.

See application note AN-619: Using the ADN8810 Demo Board (v2.0) for detailed instructions on using the ADN8810 demo board.
