RRIO, High Output Current & Unlimited Cap Load Op Amp
in SOT23-5
General Description
The SM73301 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 com-
mon 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 pan-
el TFT panel V_COM driver applications as well as being suit-
able 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 parameters
are insensitive to power supply variations; this design en-
hancement is yet another step in simplifying its usage. The
output stage has low distortion (0.05% THD+N) and can sup-
ply a respectable amount of current (15mA) with minimal
headroom from either rail (300mV).
The SM73301 is offered in the space saving SOT23-5 pack-
age.
