LMC7101
- Tiny 5-Pin SOT-23 package saves space; typical circuit layouts take half the space of 8-pin SOIC designs
- Specified for 2.7V, 3V, 5V, and 15V supplies
- Typical supply current 0.5mA at 5V
- Typical total harmonic distortion of 0.01% at 5V
- 1MHz gain bandwidth
- Specified to industrial temperature: –40°C to +85°C
- Similar to popular LMC6482 and LMC6484
- Rail-to-rail input and output
The LMC7101 device is a high-performance, automotive, CMOS operational amplifier available in a space-saving, 5-pin, SOT-23 tiny package. This design makes the LMC7101 an excellent choice for space- and weight-critical designs. The performance is similar to the single amplifier of the LMC6482 and LMC6484, 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 needed, thus simplifying board layout.
