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 out-
put 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. Full-scale and
scaled output currents are given in Equations 1 and 2,
respectively.
