Description

The XTR111 is a precision voltage-to-current converter designed for the standard 0mA to 20mA or 4mA to 20mA analog signals, and sources up to 32mA. The ratio between input voltage and output current is set by a single resistor, RSET. The circuit can also be modified for voltage-output operation. An external P-MOSFET transistor provides high output resistance and a broad-compliance voltage range that extends from 2V less than the supply voltage, VVSP, to voltages far less than ground. The adjustable 3V to 15V subregulator output provides the supply voltage for additional circuitry. The XTR111 is available in 10-pin HVSSOP and VSON surface-mount packages.
