1FEATURES DESCRIPTION

The XTR111 is a precision voltage-to-current 2• EASY-TO-DESIGN INPUT/OUTPUT RANGES:

0mA–20mA, 4mA–20mA, 5mA–25mA AND converter designed for the standard 0mA–20mA or

VOLTAGE OUTPUTS 4mA–20mA analog signals, and can source up to

36mA. The ratio between input voltage and output • NONLINEARITY: 0.002% current is set by the single resistor RSET. The circuit

• LOW OFFSET DRIFT: 1μV/°C can also be modified for voltage output.

• ACCURACY: 0.015%

An external P-MOSFET transistor ensures high

• SINGLE-SUPPLY OPERATION output resistance and a broad compliance voltage

• WIDE SUPPLY RANGE: 7V to 44V range that extends from 2V below the supply voltage,

• OUTPUT ERROR FLAG (EF) VVSP, to voltages well below GND.

• OUTPUT DISABLE (OD) The adjustable 3V to 15V sub-regulator output

• ADJUSTABLE VOLTAGE REGULATOR: provides the supply voltage for additional circuitry.

3V to 15V

The XTR111 is available in MSOP and DFN

surface-mount packages. APPLICATIONS
