Current to Voltage Converter
A simple converter to go from volts to amps. This enables high-speed (approx 10MHz) current measurement of the current used by a device. Measurement can be used on an oscilloscope, a volt-meter, or an ADC. Designed to monitor low-power mode transitions for a microcontroller project.
There are three current ranges, selectable through a switch: nA, uA, and mA, with output linear across the range:
- nanoAmp range: 1nA = 1mV, 1uA = 1V, max 5uA
- microAmp range: 1uA = 1mV, 1mA = 1V, max 5mA
- milliAmp range: 1mA = 1mV, 1A = 1V, max 5A
The output from the current-shunt is routed to a BNC for direct connection to an oscilloscope, or to an external jumper header.
Power comes from the 5V USB or from an external jumper header.
