LM8262 Dual RRIO, High Output Current & Unlimited Cap Load Op Amp in MSOP
June 2002
LM8262 Dual
RRIO, High Output Current & Unlimited Cap Load Op
Amp in MSOP
General Description
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 and guaranteed high speed
and slew rate. It is specifically designed to handle the re-
quirements 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 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. In addition, most device parameters are insen-
sitive 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 respect-
able amount of current (15mA) with minimal headroom from
either rail (300mV).
The LM8262 is offered in the space saving MSOP package.
