QAD650: Can AD650 Voltage to Frequency converter be used as a Frequency to
AYes, Like other charge-balanced VFCs,the AD650 can be used in a reverse mode as
a frequency-to-voltage (F/V) converter. We have an application note covering
this. Please refer to the application note AN-279: Using the AD650
Voltage-to-Frequency Converter As a Frequency-to-Voltage Converter. This
application note discusses the F/V architecture and operation,component
selection, a design example, and the trade-off between output ripple and
circuit response time.
