1 / 19 page  LM8261 Single RRIO, High Output Current & Unlimited Cap Load Op Amp in SOT23-5 General 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 V COM 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 function- ality under extreme conditions and offers flexibility of use in multitude of applications. In addition, most device param- eters 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 pack- age.
