Typical Application Example
Operational Notes:
*
VCO is assumed AC coupled.

may be AC or DC coupled. AC coupling is recommended because the input circuit provides its own bias. (See Figure below)
Layout Hints:
TL/W/12339–28
Proper use of grounds and bypass capacitors is essential to achieve a high level of performance.
Crosstalk between pins can be reduced by careful board layout.
This is a static sensitive device. It should be handled only at static free work stations.
