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 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, 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
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.
