Dual, 32-V, 900-kHz, 3-mV offset voltage operational amplifier with internal reference

The TL103Wx devices combine the

building blocks of a dual operational amplifier and a fixed voltage reference – both

of which are often used in the control circuitry of switch-mode and linear power

supplies. OP AMP1 has the noninverting input internally tied to a fixed 2.5V

reference, while OP AMP2 is independent, with both inputs uncommitted.

The upgraded TL103WB features

improvements such as a wider supply range (up to 36V), lower supply current

(275µA/amp) and tighter voltage regulation. This regulation can be achieved through

low offset voltages for both operational amplifiers (0.3mV typical) and tight

tolerances for the voltage reference (0.44% at 25°C and 1.04% over operating

temperature range).

The TL103WB has a widened temperature

range of –40°C to 125°C.
