Description

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. Write channels amplify the positive currents supplied at its reference inputs IN2, IN3, and IN4 by a fixed factor of 240.An on-chip RF oscillator is provided for the reduction of laser mode hopping noise.
The ZL40511 offers higher tolerance performance.
