说明

XTR105 是一款带有两个精准电流源的单片 4-20mV,2 线制电流发送器。 它提供针对铂 RTD 温度传感器和桥、仪表放大器、和一个单集成电路上的电流输出电路的完整电流激励。

多用途线性化电流提供一个对 RTD 的第二阶修正,通常可以实现一个 40:1 的线性改进。

仪器放大器增益可针对宽范围的温度或者压力测量进行配置。整个电流发送器的总体未调整误差足够低以允许在未
经调整的情况下用于很多应用。这包括零输出电流漂移,和非线性。XTR105 在环路电源电压上运行。

The XTR105 is a monolithic 4-20mA, 2-wire current transmitter with two precision current sources. It provides complete current excitation for platinum RTD temperature sensors and bridges, instrumentation amplifiers, and current output circuitry on a single integrated circuit.

Versatile linearization circuitry provides a 2nd-order correction to the RTD, typically achieving a 40:1 improvement in linearity.

Instrumentation amplifier gain can be configured for a wide range of temperature or pressure measurements. Total unadjusted error of the complete current transmitter is low enough to permit use without adjustment in many applications. This includes zero output current drift, span drift, and nonlinearity. The XTR105 operates on loop power-supply voltages down to 7.5V.

The XTR105 is available in DIP-14 and SO-14 surface-mount packages and is specified for the –40°C to +85°C industrial temperature range
