Description 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 0.97mA 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 50dB of Common Mode Rejection, allows high side and low side
sensing, among many applications, without having any concerns over exceeding the range and no compromise in accuracy. Exceptionally
wide operating supply voltage range of 2.5V to 30V alleviates any concerns over functionality under extreme conditions and
offers flexibility of 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 (15mA) with minimal headroom from either rail (300mV).
The LM8261 is offered in the space saving SOT23-5 package.
