The XTR112UA is a monolithic 4-20mA current transmitter designed for industrial applications, featuring two precision current sources of 250¬µA. It provides complete current excitation for high impedance platinum RTD temperature sensors and bridges, along with instrumentation amplifier and current output circuitry integrated into a single package. The device supports versatile linearization circuitry that offers a second-order correction to the RTD, typically improving linearity by 40:1. With a low total unadjusted error, the XTR112UA can be used without adjustment in many applications, ensuring minimal drift in zero output current and span. It operates over a wide supply voltage range of 7.5V to 36V and is specified for an industrial temperature range of -40¬8C to +85¬8C. The device is available in an SO-14 surface-mount package, making it suitable for various applications including industrial process control, factory automation, and remote data acquisition systems.
