The TPA9151 is a general-purpose, unity-gain difference amplifier for precision signal conditioning from −275 V to 275 V common voltage range. The onchip 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.
Features
Supply Voltage: 4.5 V to 36 V (±2.25 V to ±18 V)
Offset Voltage: ±1 mV Maximum
Gain Error: 0.03% Maximum
Bandwidth: 500 kHz, Slew Rate: 10 V/μs
EMI Enhancement
−40°C to 125°C Operation Temperature Range
Applications
Current sense on high common voltage
Battery voltage monitor
Industrial control
