Part Number: VCA2615
My customer is considering to use the VCA2615.
They would like to understand points to note when using in the 300 kHz frequency band of the VCA2615.
In the data sheet, the lower frequency limit is cut at 500 kHz as shown in Figure11 and Figure 12.
Since this IC was originally intended to be used in the MHz band, they believe that it is not displayed.
As shown in Figure 15, when using in the frequency band of 500 kHz or less, it is recognized that it is necessary to pay attention to at least the capacitance value of the external Cext. Are there any other points to note?
Although there is no specific description in the data sheet, they think it is likely that it is better to increase the capacitance of the bypass capacitor (the current design of 2MHz is based on the EVM of VCA2615) as the frequency decreases.
