Description

The ZT7661AS is a high-performance three-channel laser driver specifically designed for controlling the current of a grounded laser diode. It offers switching speeds of approximately one nanosecond rise/fall time, with channels 2 and 3 recommended for write channels. All three channels can be combined at the IOUT output, allowing users to create multilevel waveforms to optimize laser diode performance.
