3 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 0.97 mA 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 50 dB of Common Mode Rejection allows
high side and low side sensing, among many
applications, without concern over exceeding the
range and with no compromise in accuracy.
Exceptionally wide operating supply voltage range of
2.5 V to 30 V alleviates any concerns over
functionality under extreme conditions and offers
flexibility for 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 output
stage has low distortion (0.05% THD+N) and can
supply a respectable amount of current (15 mA) with
minimal headroom from either rail (300 mV).
The LM8261 is offered in the space-saving SOT-23-5
package.
