NSC LM8262MMX

LM8262 Dual
RRIO, High Output Current & Unlimited Cap Load Op
Amp in MSOP
General Description
Features
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 requirements of flat panel TFT panel VCOM 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 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).
(VS = 5V, TA = 25˚C, Typical values unless specified).

+/−11V Electrical Characteristics
(Continued)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Rating indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5kΩ in series with 100pF.
Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C.
Note 4: The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(max) - TA)/ θJA. All numbers apply for packages soldered directly onto a PC board.
Note 5: Typical Values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: Positive current corresponds to current flowing into the device.
Note 8: Slew rate is the slower of the rising and falling slew rates. Connected as a Voltage Follower.
Note 9: Machine Model, 0Ω is series with 200pF.
Note 10: Short circuit test is a momentary test. See Note 11.
Note 11: Output short circuit duration is infinite for VS ≤ 6V at room temperature and below. For VS > 6V, allowable short circuit duration is 1.5ms.
Note 12: Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
