●Cautions on use (2/2)
[BH7659FS]
13) External resistance for analog SW block
The frequency characteristics of analog switches vary according to the output load capacity.
Set an external resistance value of R0 to keep frequency characteristics as flat as possible.
14) Polarity of input coupling capacitor
When this IC is switched, variation is approximately 3.5 V when the input pin's DC voltage has been selected, but is 0 V
when the input pin's DC voltage has not been selected. Therefore, the input coupling capacitor's polarity should be set so
as to avoid applying a reverse voltage to capacitors, whether the input pin's DC voltage has been selected or not.
15) High frequency characteristics of input coupling capacitor
Since this IC handles signals at very high frequencies, when using an electrolytic capacitor as a coupling capacitor for
input, be sure to insert high-frequency oriented ceramic capacitors (approximately 0.01 µF) in parallel.
16) Layout of target board
Since this IC handles signals at very high frequencies, be sure to insert the power supply pin's decoupling capacitor close to
the IC's power supply pin. Also, use as large a GND pattern as possible.
