SBOS375C –NOVEMBER 2006–REVISED JUNE 2011

Precision Voltage-to-Current

Converter/Transmitter

Check for Samples: XTR111

FEATURES

DESCRIPTION

The XTR111 is

precision voltage-to-current

•

EASY-TO-DESIGN INPUT/OUTPUT RANGES:

0mA–20mA, 4mA–20mA, 5mA–25mA AND

VOLTAGE OUTPUTS

NONLINEARITY: 0.002%

LOW OFFSET DRIFT: 1μV/°C

ACCURACY: 0.015%

SINGLE-SUPPLY OPERATION

WIDE SUPPLY RANGE: 7V to 44V

OUTPUT ERROR FLAG (EF)

OUTPUT DISABLE (OD)

ADJUSTABLE VOLTAGE REGULATOR:

3V to 15V

converter designed for the standard 0mA–20mA or

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

36mA. The ratio between input voltage and output

current is set by the single resistor R_SET. 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,

V_VSP, to voltages well below GND.

The adjustable 3V to 15V sub-regulator output

provides the supply voltage for additional circuitry.

The XTR111 is available in MSOP and DFN

surface-mount packages.
