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.
