The TL103Wx devices combine the building blocks of a dual operational amplifier and a fixed voltage reference – both of which are often used in the control circuitry of switch-mode and linear power supplies. OP AMP1 has the noninverting input internally tied to a fixed 2.5V reference, while OP AMP2 is independent, with both inputs uncommitted.
The upgraded TL103WB features improvements such as a wider supply range (up to 36V), lower supply current (275µA/amp) and tighter voltage regulation. This regulation can be achieved through low offset voltages for both operational amplifiers (0.3mV typical) and tight tolerances for the voltage reference (0.44% at 25°C and 1.04% over operating temperature range).
The TL103WB has a widened temperature range of –40°C to 125°C.
