3 Description

The LMC7101 device is a high-performance CMOS operational amplifier available in the space-saving 5-pin SOT-23 tiny package. This makes the LMC7101 ideal for space- and weight-critical designs. The performance is similar to a single amplifier of the LMC6482 and LMC6484 types, with rail-to-rail input and output, high open-loop gain, low distortion, and low-supply currents.

The main benefits of the tiny package are most apparent in small portable electronic devices, such as mobile phones, pagers, notebook computers, personal digital assistants, and PCMCIA cards. The tiny amplifiers can be placed on a board where they are needed, thus simplifying board layout.
