The TSM104W combines the building blocks of a quad operational amplifier and an adjustable voltage reference, both of which often are used in the control circuitry of switch-mode power supplies.
For the A grade, especially tight voltage regulation can be achieved through the low offset voltage for each operational amplifier (typically 0.5 mV) and tight tolerance for the voltage reference (0.4% at 25°C and 0.8% over operating temperature range).
The TSM104W and TSM104WA are characterized for operation from -40°C to 105°C.
