GENERAL DESCRIPTION

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.

Noise and digital feedthrough are kept low to ensure low jitter

operation for laser diode applications. Full-scale and scaled

output currents are given in Equation 1 and Equation 2,

respectively.

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 serial

peripheral interface (SPI). The 3-bit address allows up to eight

devices to be independently controlled while attached to the

same SPI bus.
