LM8272 Dual
RRIO, High Output Current & Unlimited Cap Load Op
Amp in Miniature Package
General Description
The LM8272 is a Rail-to-Rail input and output OpAmp 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 while requiring only 0.95mA/channel supply cur-
rent. It is specifically designed to handle the requirements of
flat panel TFT panel V
driver applications as well as
being suitable for other low power, and medium speed ap-
plications which require ease of use and enhanced perfor-
mance 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 24V 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 LM8272 is offered in the 8-pin MSOP package.
