2 V Input Isolated Amplifier


The TPA8023 is a precision, isolated amplifier with an output separated from the input circuitry by capacitive silicon dioxide insulation barrier. This barrier is certified to provide isolation of up to 3750VRMS according to UL1577.

The common mode transient immunity (CMTI) of the TPA8023 has been significantly enhanced through innovative circuit design and optimized structure.

The input of the TPA8023 is high-impedance which can be connected to high-impedance resistive dividers or any other high-impedance voltage signal source. The excellent performance of the device supports bus voltage in motor control or other applications. The common-mode overvoltage and missing high-side supply voltage detection features of the TPA8023 simplify system-level diagnostics.

The device is available in SOP8 packages, and is characterized from −40°C to +125°C.
