The LM8262 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 high speed and slew rate. The device is designed to handle the requirements of flat panel TFT panel VCOM driver applications as well as being designed 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 90dB of common mode rejection allows high side and low side sensing for many applications without concern for exceeding the range and with no compromise in accuracy. In addition, most device parameters are insensitive to power supply variations. This design enhancement is yet another step in simplifying the usage. The output stage has low distortion (0.00022% THD+N) and has a high short-circuit output current of 125mA/channel.

The LM8262 is offered in the space-saving VSSOP package.
