Product Summary
The AD6521ACA is a Synchronous Voltage-to-Frequency Converter (SVFC). The AD6521ACA is a powerful building block for precision analog-todigital conversion, offering typical nonlinearity of 0.002% (0.005% maximum) at a 100 kHz output frequency. The inherent monotonicity of the transfer function and wide range of clock frequencies allows the conversion time and resolution to be optimized for specific applications. The AD6525ACA uses a variation of the popular charge-balancing technique to perform the conversion function. The AD6525ACA uses an external clock to define the full-scale output frequency, rather than relying on the stability of an external capacitor. The result is a more stable, more linear transfer function, with significant application benefits in both single- and multichannel systems.
