Description

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 5000VRMS

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 common-mode overvoltage and

missing high-side supply voltage detection features

of the TPA8003 simplify system-level diagnostics.

The device is available in WSOP8 packages, and is

characterized from −40°C to +125°C.
