в—Џ CURRENT AMPLIFIER
в—Џ VOLTAGE-TO-CURRENT AMPLIFIER DESCRIPTION used for offsetting or to excite transducers. A current
return pin (IRET) senses any current used in external
circuitry to assure an accurate control of the output
current.
The XTR115 is a fundamental building block of
smart sensors using 4-to-20mA current transmission. …
