LM8272MM/NOPB 运算放大器 - 运放 RRIO HI OTPT UNLIMIT CAP LOAD OP AMP

1 Features 3 Description

1(V The LM8272 is a Rail-to-Rail input and output Op S = 12V, TA = 25°C, Typical values unless

specified). Amp which can operate with a wide supply voltage

range. This device has high output current drive,

• GBWP 15MHz greater than Rail-to-Rail input common mode voltage

• Wide supply voltage range 2.5 V to 24 V range, and unlimited capacitive load drive capability,

while requiring only 0.95mA/channel supply current. It • Slew rate 15 V/μs

is specifically designed to handle the requirements of

• Supply current/channel 0.95 mA flat panel TFT panel VCOM driver applications as well

• Cap load tolerance Unlimited as being suitable for other low power and medium

• Output short circuit current ±13 0mA speed applications which require ease of use and

enhanced performance over existing devices. • Output current (1 V from rails) ±65 mA

• Input common mode voltage 0.3 V beyond rails Greater than Rail-to-Rail input common mode voltage

range with 50 dB of Common Mode Rejection allows

• Input voltage noise 15 nV/√Hz high side and low side sensing among many

• Input current noise 1.4 pA/√Hz applications without concerns for exceeding the range

and with no compromise in accuracy. An

2 Applications exceptionally wide operating supply voltage range of

2.5 V to 24 V removes any concerns over • TFT-LCD flat panel VCOM driver functionality under extreme conditions and offers

• A/D converter buffer flexibility of use in multitude of applications. In

• High side/low side sensing addition, most device parameters are insensitive to

power supply variations. This design enhancement is • Headphone amplifier

yet another step in simplifying its usage.

The LM8272 is offered in the 8-pin VSSOP package.
