12-Bit High Output Current Source
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.
