TPA9151 ±275 V Common Mode Voltage Difference Amplifier
3PEAK’s unity gain difference amplifier provides a gain error of ±0.03% over -40°C to +125°C
3PEAK's 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.
