Description

The ZL40539 is a high performance laser diode driver capable of driving two separate cathode grounded laser diodes (e.g., 650 nm and 780 nm laser diodes).

The ZL40539 contains a 150 mA low noise read channel (ChR), and three >450 mA write channels (Ch2, Ch3 and Ch4). Each channel amplifies the positive current supplied at its reference input (INR, IN2, IN3, IN4) by a fixed factor of 100, 250, 150 and 100 respectively.
