TPA9151 275V Common Voltage Difference Amplifier

Description 

The TPA9151 is a general-purpose, unity-gain  difference amplifier for precision signal conditioning  from −275 V to 275 V common voltage range. The  on-chip resistors are trimmed for excellent gain  accuracy and high CMRR over the operating  temperature range.  

The device can be used to replace isolation amplifiers  in applications if the galvanic isolation is not required.
