ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
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.

DESCRIPTION
The XTR111 is a precision voltage-to-current 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 RSET. The circuit can also be modified for voltage output.
