Hi , i should use a TC9402 (microchip) to convert very slow frequency to voltage.
My frequency range in between DC and 5 Hz... and i have some questions:
1) at page 1 of the datasheet they says "Operation: DC to 100 kHz", but at page 4 "Input FrequencyRange" section they says 10Hz to 100KHz... what are the right values ?2) I want to try the schematic at page 16 with single supply (12V): the equation:VOUT = [VREF CREF RINT] FIN If want to get 1V/Hz , is it right to set: vref=5V cref=10u and Rint=20K ?
thanks to all...
