Universal Industrial Output Driver - Texas Instruments

Texas Instruments introduced the The XTR111, a precision voltage-to-current converter. The XTR111 features low supply (500uA), low drift span (5ppm/C) and a wide 7V to 44V supply range. The XTR111 is adaptable to many applications such as analog current output for industrial process control and three-wire sensor systems.

The XTR111 can pre-condition sensor signals through digitally calibrated sensor signal conditioning chips, ultra low-power microcontrollers, and discrete combinations of instrumentation amplifiers and voltage references, or low-power op amps and voltage references. The ratio of in/out voltage and current can be set via an external resistor. With accuracy of 0.015 percent, the chip is suitable for voltage-controlled current source and current-mode sensor excitation circuits.

The XTR111 is available now in a DFN-10 micro-package. An MSOP-10 package will be available in mid  2007. The price is US$1.45 each (1K)
