Introduction
The AND -VFC-30 voltage-to-frequency converter (VFC) is a powerful building block for precision analog-to-digital conversion, offering typical nonlinearity of 0.005% (0.01% maximum) at a 200 kHz output frequency. The module does not need to connect any additional components and can continuously convert three current signals at the same time.
Features
Ultra-low offset
Minimal nonlinear error
Adjustable current measurement range
No critical external components required
Low power consumption
Voltage or current input
