The XTR112UA is a monolithic 4-20mA current transmitter designed for industrial applications, featuring two precision current sources of 250µA. 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°C to +85°C. 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.
