LM8272

SNOS515F –OCTOBER 2000–REVISED AUGUST 2015

LM8272 Dual RRIO, High Output Current & Unlimited Cap Load

Op Amp in Miniature Package

1 Features

3 Description

The LM8272 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, and unlimited capacitive load drive capability,

while requiring only 0.95mA/channel supply current. It

is specifically designed to handle the requirements of

flat panel TFT panel V_COMdriver 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.

(V_S= 12V, T_A= 25°C, Typical values unless

specified).

•

GBWP 15MHz

Wide supply voltage range 2.5 V to 24 V

Slew rate 15 V/µs

Supply current/channel 0.95 mA

Cap load tolerance Unlimited

Output short circuit current ±13 0mA

Output current (1 V from rails) ±65 mA

Input common mode voltage 0.3 V beyond rails

Input voltage noise 15 nV/√Hz

Input current noise 1.4 pA/√Hz

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 concerns for exceeding the range

and with no compromise in accuracy. An

exceptionally wide operating supply voltage range of

functionality 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 enhancement is

yet another step in simplifying its usage.
