2.2-V Input Isolated Amplifier


The TPA8003 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 5000-VRMS according to UL1577.

The common mode transient immunity (CMTI) of the TPA8003 has been significantly enhanced through innovative circuit design and optimized structure.

The input of the TPA8003 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 feature of the TPA8003 detecting whether high-side supply voltage is missing or not simplifies system-level diagnostics.

The device is available in the WSOP8 package, and is characterized from −40°C to +125°C.
