The SGM41295S provides DC bias for the laser diode, EA bias, and MPD bias monitor circuits, and it also provides an unregulated negative output generated by an inverting charge pump which is equal to negative input voltage. The
SGM41295S is available in a Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40℃ to +105℃.
