XTR103BU数据手册TI中文资料规格书

描述 Description

DESCRIPTION
The XTR103 is a monolithic 4-20mA, two-wire current transmitter designed for Platinum RTD temperature sensors. It provides complete RTD current excitation, instrumentation amplifier, linearization, 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.FEATURES
