ADN8810ACPZ

ADN8810 is a 12-bit current source with an adjustable full-scale output current of up to 300mA. The full-scale output current is set with two external sense resistors. The output compliance voltage is 2.5V, even at output currents up to 300mA. 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. Application includes tunable laser current source, programmable high output current source, automatic test equipment.
