Conversor de tensão-corrente de precisão IC Texas Instruments XTR110KP PDIP-16

The Texas Instruments XTR110KP is a precision voltage-to-current converter IC in a PDIP-16 package designed for industrial signal transmission. It transforms a measured or control voltage into a proportional current suitable for 4–20 mA current loops and remote sensor interfaces. The device provides stable current sourcing and is intended for use in process control, instrumentation, and long-distance analog signalling where accurate current output and low drift are required.

Advantages

The XTR110KP offers precision voltage-to-current conversion with low temperature drift and high output compliance, enabling reliable operation across a range of industrial conditions. Its integrated design reduces external component count and simplifies loop wiring for 4–20 mA systems. The PDIP-16 package provides easy handling and straightforward through-hole mounting for prototyping and legacy board designs. The converter supports stable current sourcing for sensors and transmitters, improving signal integrity over long cable runs.
