Product Details
●The ADN8810 is a 12-bit current source with an adjustable full-scale output current of up to 300 mA. The full-scale output current is set with two external sense resistors. The output compliance voltage is 2.5 V, even at output currents up to 300 mA.
●The device is particularly suited for tunable laser control and can drive tunable laser front mirror, back mirror, phase, gain, and amplification sections. A host CPU or microcontroller controls the operation of the ADN8810 over a 3-wire SPI interface. The 3-bit address allows up to eight devices to be independently controlled while attached to the same SPI bus.
●The ADN8810 is guaranteed with ±4 LSB INL and ±0.75 LSB DNL. Noise and digital feedthrough are kept low to ensure low jitter operation for laser diode applications.
