Description Features
 
Triple Laser Switch iC-HB enables the spike-free switching of laser diodes with well-defined current pulses at frequencies ranging from DC to 155 MHz.

The diode current is determined by the voltages at pins CIx.  The three fast switches are controlled independently via LVDS/TTL inputs. Input TTL = hi selects TTL type inputs. The laser diode can thus be turned on and off or switched between different current levels (LDKx connected) defined by the voltages at CI1, CI2 and CIB. Channel B is preferably used for biasing. For current monitoring purpose IMON sinks a fraction of the sum of currents into LDKx.  

Each channel can be operated at 65mA DC (channel B: 60 mA) and up to 300mA (channel B: 275 mA) pulsed current depending on the frequency, duty cycle and heat dissipation. The integrated thermal shutdown feature protects the IC from damage by excessive temperature.
