XTR108 具有“智能”可编程信号调节的 4-20mA 两线制发送器
The XTR108 is a "smart", programmable, 4-20mA, two-wire transmitter designed for temperature and bridge sensors. Zero, span, and linearization errors in the analog signal path can be calibrated via a standard digital serial interface, eliminating manual trimming. Non-volatile ex-ternal EEPROM stores calibration settings.
The all-analog signal path contains an input multiplexer, autozeroed programmable-gain instrumentation amplifier, dual programmable current sources, linearization circuit, voltage reference, sub-regulator, internal oscillator, control logic, and an output current amplifier. Programmable level shifting compensates for sensor DC offsets. Selectable up- and down-scale output indicates out-of-range and burn-out per NAMUR NE43
