Howland current converter

Web31 mei 2016 · Voltage-to-current converters are circuits which convert an input voltage into an output current. The output current is usually proportional to the input voltage, over some suitable range. Many of these circuit designs use op-amps. Please see the Op-Amp page for more general information on operational amplifiers. 2. WebElectrical – Bipolar Voltage to Current Converter. I need a circuit or component which converts bipolar voltage to bipolar current. I have found the XTR111 from Texas Instruments and the 1B22 from Analog Devices. However, they only convert 0-10 V to 0-20 mA current. I to need convert -10V-0V to -10mA-0mA too (the opposite polarity range).
