Overview
The LM248DT, produced by STMicroelectronics, is a quad operational amplifier consisting of four independent, high-gain, internally-compensated, low-power operational amplifiers. These amplifiers are designed to provide functional characteristics identical to those of the familiar UA741 operational amplifier. The total supply current for all four amplifiers is compatible with the supply current of a single UA741 type operational amplifier, making it an efficient choice for applications requiring multiple amplifiers.
