ZL40511 Overview
The ZL40511/15 are high performance laser drivers capable of driving two separate cathode grounded laser diodes (e.g., 650 nm and 780 nm laser diodes). The ZL40511/15 contain a 150 mA low-noise read channel (ChR), and three 500 mA write channels (Ch2, Ch3 and Ch4). The read channel amplifies the positive current supplied at its reference input, INR, by a fixed factor of 100.
