XTR101 高精度、低漂移 4-20mA 两线制发送器
The XTR101 is a microcircuit, 4-20mA, two-wire transmitter containing a high accuracy instrumentation amplifier (IA), a voltage-controlled output current source, and dual-matched precision current reference. This combination is ideally suited for remote signal conditioning of a wide variety of transducers such as thermocouples, RTDs, thermistors, and strain gauge bridges. State-of-the-art design and laser-trimming, wide temperature range operation, and small size make it very suitable for industrial process control applications. In addition, the optional external transistor allows even higher precision.
The two-wire transmitter allows signal and power to be supplied on a single wire pair by modulating the power-supply current with the input signal source
