The TL103W and TL103WA combine the building blocks of a dual operational amplifier and a fixed voltage reference – both of which often are used in the control circuitry of both switch-mode and linear power supplies. OP AMP1 has its noninverting input internally tied to a fixed 2.5-V reference, while OP AMP2 is independent, with both inputs uncommitted.
For the A grade, especially tight voltage regulation can be achieved through low offset voltages for both operational amplifiers (typically 0.5?mV) and tight tolerances for the voltage reference (0.4% at 25°C and 0.8% over operating temperature range).
The TL103W and TL103WA are characterized for operation from –40°C to 105°C.
