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. The operational amplifier features low offset voltage, low supply current, unity gain bandwidth, etc. The voltage reference features a fixed 2.5V reference voltage, low temperature drift, wide output current range, etc.
The TL103W and TL103WA combine a dual operational amplifier and a fixed 2.5-V voltage reference in a single package. The device features low offset voltage and low supply current, making it suitable for battery chargers, switch-mode power supplies, and data-acquisition systems. OPAMP1 has its noninverting input internally tied to the 2.5-V reference, while OPAMP2 is independent.
