DESCRIPTION
The XTR115 and XTR116 are precision current output converters designed to transmit analog 4-to-20mA signals over an industry standard current loop.
They provide accurate current scaling and output current limit functions.
The on-chip voltage
regulator (5V) can be used to power external circuitry.
A precision on-chip VREF (2.
