What is the minimum current and voltage the ADALM1000 can reliably output?
Also, what is the minimum current and voltage the ADALM1000 can reliably measure?
Do these values differ when using Alice, Python, Matlab, or Pixelpulse2?
ADALM1000 uses 16bit converters ( AD5663R for digital to analog conversion and AD7682 for analog to digital conversion) and offers voltage and current operation from 0 to 5 Volts (V), from -200 to 200 milliamps (mA).
The measured values should not differ depending on the software you use.
Thank you for your response.
While the board may use 16-bit converters, it's practical resolution is not 16-bit, as stated in the link you provided. There it says the lowest measurable current is closer to 100 uA, or 12-bit. What is the lowest measurable voltage accounting for noise?
In the following link it states "The practical range of test currents from the source in the M1K is 5 mA to 150 mA (or slightly higher)" which was written by dmercer, same user in the link you provided above.
Is it possible to output currents lower than 5 mA with the ADALM1000 using external circuitry?
You asked: "Is it possible to output currents lower than 5 mA with the ADALM1000 using external circuitry?"
The short answers is yes, the operative word being external, depending on the application.
The m1k like any adjustable voltage source / function generator can be used as the control voltage for a voltage to current converter. Do a web search on such circuit techniques, like the well known Howland Current Pump or Source. As a matter of fact ADI supplies the following integrated circuit version.
