XTR111AIDRCT

The XTR111AIDRCT is a Precision Voltage-to-Current Converter/Transmitter, designed for the standard 0 to 20mA or 4 to 20mA analogue signals and can source up to 36mA. The ratio between input voltage and output current is set by the single resistor RSET. The circuit can also be modified for voltage output. An external P-MOSFET transistor ensures high output resistance and a broad compliance voltage range that extends from 2V below the supply voltage, VVSP, to voltages well below GND. The adjustable 3 to 15V sub-regulator output provides the supply voltage for additional circuitry.

• Easy-to-design input/output ranges - 0 to 20, 4 to 20, 5 to 25mA and voltage outputs
• 0.002% Nonlinearity
• 1µV/°C Low offset drift
• 0.015% Accuracy
• Single-supply operation
• Output error flag (EF)
• Output disable (OD)
• 3 to 15V Adjustable voltage regulator
