275V Common Voltage Difference Amplifier

Description

Features

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.

 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

The device can be used to replace isolation amplifiers

in applications if the galvanic isolation is not required.

Applications

 Current sense on high common voltage

 Battery voltage monitor

 Industrial control
