采用 SOT23-5 封装的 RRIO、高输出电流和无限负载电容运算放大器

 

描述

The LM8261 is a Rail-to-Rail input and output Op Amp which can operate with a wide supply voltage range. This device has high output current drive, greater than Rail-to-Rail input common mode voltage range, unlimited capacitive load drive capability, and provides tested and guaranteed high speed and slew rate while requiring only 0.97 mA supply current. It is specifically designed to handle the requirements of flat panel TFT panel VCOM driver applications as well as being suitable for other low power, and medium speed applications which require ease of use and enhanced performance over existing devices.

Greater than Rail-to-Rail input common mode voltage range with 50 dB of Common Mode Rejection allows high side and low side sensing, among many applications, without concern over exceeding the range and with no compromise in accuracy. Exceptionally wide operating supply voltage range of 2.5 V to 30 V alleviates any concerns over functionality under extreme conditions and offers flexibility for use in multitude of applications. In addition, most device parameters are insensitive to power supply variations; this design enhancement is yet another step in simplifying its usage. The output stage has low distortion (0.05% THD+N) and can supply a respectable amount of current (15 mA) with minimal headroom from either rail (300 mV).

The LM8261 is offered in the space-saving SOT-23-5 package.
