> 16V to fully enhance output transistor. Otherwise out current must be derated - see graphs. Operation at low supply may cause excessive heating
due to increased on-resistance. Tested at 7V guaranteed for 6V by design.
5. ZXLD1356 will operate at higher frequencies but accuracy will be affected due to propagation delays.
