TL103W, TL103WA
SLOS437M – APRIL 2004 – REVISED OCTOBER 2016
TL103W Dual Operational Amplifiers
With Internal Reference
1 Features
3 Description
•
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.

2 Applications
•
•
•
•
Battery Chargers
Switch-Mode Power Supplies
Linear Voltage Regulation
Data-Acquisition Systems
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.
