The flexible serial interface is SPI, MICROWIRE™, QSPI™, and DSP compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications.The device also includes a power-on reset function, ensuring that the device powers up in a known state, and an asynchronous CLEAR pin that sets the output to the low end of the selected current range.
The total unadjusted error is typically ±0.01% FSR.
