3 Description
The LM8272 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, and unlimited capacitive load drive capability,
while requiring only 0.95mA/channel 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 concerns for exceeding the range
and with no compromise in accuracy. An
exceptionally wide operating supply voltage range of
2.5 V to 24 V removes 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 LM8272 is offered in the 8-pin VSSOP package.
