Description：

The TPA8003 is a precision, isolated amplifier with anoutput separated from the input circuitry by the capacitivesilicon dioxide insulation barrier. This barrier is certified toprovide isolation of up to 5000 VRMS according to UL 1577.The common-mode transient immunity (CMTI) of theTPA8003 is significantly enhanced through innovativecircuit design and optimized structure.The input of the TPA8003 is high-impedance which canbe connected to high-impedance resistive dividers or otherhigh-impedance voltage signal sources. The excellentperformance of the device supports the bus voltage inmotor control or other applications. The feature of theTPA8003 detecting whether high-side supply voltage ismissing or not simplifies system-level diagnostics.The device is available in the WSOP8 package, and ischaracterized from −40°C to +125°C.
