Texas Instruments 計装アンプ, 10-Pin HTSSOP

The Texas Instruments 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.
