XTR110 Voltage-Current Converter
As shown in the picture, when the output current exceeds 40mA the internal resistance 50? in the XTR110 (R9) should be replaced by external resistance REXT. REXT is connected between the 13 foot and 16 foot. REXY=R9(original span/required span). For example, the XTR110 in the picture`s original span is 20mA and now the required span is 10A. If R9=50?, then..
voltage to current convertor
his Circuit converts a voltage control output from a Process Controller to be converted into a Current Control if the AC-Drive or Valve needs a Current Control Signal. This is a three wire voltage to current loop converter. The 1-5 V DC is attenuated and fed to pin 5 LM723 opamp section which tries to maintain the same voltage at pin 10 across the
Compensation of voltage-to-current converter
A voltage-to-current converter providing an output current with compensation for process-voltage-temperature (PVT) variations of a component in the voltage-to-current converter. The voltage-to-current converter includes a first voltage-to-current converter branch, a second voltage-to-current converter branch, and a compensation current path. The first voltage-to-current converter provides a...
High Voltage Current Mode Step-down Converter With Low Power Standby Capability
classic V/I converter
Figure 1 shows a classic voltage-to-current (V/I) converter. You can select the resistor values such that the output current in the load, RL, varies only with the input voltage, VIN, and is independent of RL. The circuit is widely used in industrial instruments for supplying a 4- to 20-mA signal. The circuit has its limitations, however, because the resistor values must be quite accurate to...
Voltage-to-current converter II
The circuit in Figure 1 performs active voltage-to-current conversion or acts as a variable-gain current mirror with high precision and bandwidth. A typical application is testing high-speed ICs or other devices that have inputs designed to be driven from current-steering DACs to enable a modulated voltage source to control the devices. The circuit thus simplifies the testing of such devices in...
The voltage-to-current converter in Figure 1 can both source and sink current. The circuit is more flexible than some traditional current references that require different topologies for current sourcing and sinking. Also, you can easily adjust the value of the current reference by simply adjusting the circuit`s input voltage.
V/I converter accommodates grounded load
The voltage-to-current (V/I) converter in Figure 1 uses three common op amps, two medium-power transistors, and only a few passive components. The first op amp (IC1) inverts the sum of voltages VIN and VOUT to V1=-(VIN+VOUT). The second op amp (IC2) and transistors Q1 and Q2 invert this voltage to produce VIN+VOUT.
