Component descriptions
Component
Functional description
Rin
Inverting input resistor that sets the closed loop gain in conjunction with Rfeed. This
resistor also forms a high pass filter with Cin (Fc = 1 / (2 x Pi x Rin x Cin)).
Cin
Input coupling capacitor that blocks the DC voltage at the amplifier input terminal.
Rfeed
Feed back resistor that sets the closed loop gain in conjunction with Rin.
Cs
Supply bypass capacitor that provides power supply filtering.
Cb
Bypass pin capacitor that provides half supply filtering.
Cfeed
Low pass filter capacitor allowing to cut the high frequency (low pass filter cut-off
frequency 1/ (2 x Pi x Rfeed x Cfeed)).
AV
Closed loop gain in BTL configuration = 2 x (Rfeed / Rin).
Exposed pad
DFN8 exposed pad is electrically connected to pin 7. See DFN8 package
information on page 28 for more information.
