The ISL58125 is a high-performance dual channel laser driver that provides controlled current to grounded laser diodes. A bias current is summed with the switched current at the IOUT output, allowing the user to optimize laser diode performance.
Output switched current flows when the LVDS signal DATA is high. The output current returns to the fixed-threshold value when DATA is low. Complete IOUT shut-off is achieved by holding both of the DISx pins Hi, which will override all other control pins.
A fast settling APC amplifier connects directly to the monitor diode. The ISL58125 does not exhibit any time-dependent droop since the calibration gain is stored as a digital number.
