Functions & Benefits

Description
The NA2100 is a voltage to frequency converter (VFC) manufactured using a CMOS process. Operating from a single supply up to 5.25 V, the NA2100 has an internal 2.5 V bandgap reference voltage, but an external reference voltage can also be used. This external reference supply range is up to VDD. The full-scale output frequency is synchronized to the clock signal on the CLKIN pin. The maximum input frequency of the NA2100 is 1 MHz; for analog input signals varying from 0 V to VREF, the output frequency varies from 10% to 90% of fCLKIN.

Applications
- Simple AD converter, simple isolated transmission, etc.
