Features (VS = 12V, TA = 25°C, Typical values unless specified). GBWP 15MHz Wide supply voltage range 2.5V to 24V Slew rate 15V/µs Supply current/channel 0.95mA Cap load tolerance Unlimited Output short circuit current ±130mA Output current (1V from rails) ±65mA Input common mode voltage 0.3V beyond rails Input voltage noise 15nV/ Input current noise 1.4pA/ 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, 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 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. Exceptionally wide operating supply voltage range of 2.5V to 24V alleviates any concerns over 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. The LM8272 is offered in the 8-pin MSOP package. Applications • TFT-LCD flat panel VCOM driver • A/D converter buffer • High side/low side sensing • Headphone amplifier

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM8272MM	VIP III	0	15575	0	0	1212500	3	344050185
LM8272MMX	VIP III	0	15575	0	0	1212500	3	344050185

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
