Description：

The TPA8023 is a precision, single-end input, single-endoutput isolated amplifier with an output separated fromthe input circuitry by a capacitive silicon dioxide insulationbarrier. This barrier is certified to provide isolation of up to3750-VRMS according to UL1577 for the SOP8 version and5000-VRMS for the WSOP8 version.The common mode transient immunity (CMTI) of theTPA8023 has been significantly enhanced throughinnovative circuit design and optimized structure.The input of the device is high-impedance which can beconnected to high-impedance resistive dividers or anyother high-impedance voltage signal source. The deviceprovides a single-end output which can be fed into singleend input of the next stage. The excellent performance ofthe device supports bus voltage in motor control or otherapplications.The device is available in both SOP8 and WSOP8packages, and is characterized from −40°C to +125°C.
