GENERAL DESCRIPTION
The ADN8810 is a 12-bit current source with an adjustable full- Noise and digital feedthrough are kept low to ensure low jitter scale output current of up to 300 mA. The full-scale output current operation for laser diode applications. Full-scale and scaled is set with two external sense resistors. The output compliance output currents are given in Equation 1 and Equation 2, voltage is 2.5 V, even at output currents up to 300 mA. respectively. The device is particularly suited for tunable laser control and VREF I (1) can drive tunable laser front mirror, back mirror, phase, gain, FS 10 RSN and amplification sections. A host CPU or microcontroller controls the operation of the ADN8810 over a 3-wire serial V 1 R REF SN I Code 0.1 (2) peripheral interface (SPI). The 3-bit address allows up to eight OUT 4096 R 15 k SN devices to be independently controlled while attached to the same SPI bus. The ADN8810 is guaranteed with ±4 LSB integral nonlinearity (INL) and ±0.75 LSB differential nonlinearity (DNL).
