TSM104WAIPWR

四通道运算放大器和可编程电压基准 QUAD OPERATIONAL AMPLIFIER AND PROGRAMMABLE VOLTAGE REFERENCE

DESCRIPON/ORDERING INFORMATION

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.
