: Components in the test circuits are only used to obtain and confirm the device characteristics. These components
and circuits do not warrant to prevent the application equipment from malfunction or failure.
*
: In addition to the low-pass filters (chebyshev LPFs) shown above, a fourth low-pass filter with a cut-off frequency
of 30 kHz is used for device characterization.
