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.
