TEST AND APPLICATION INFORMATION
Test conditions
Because the application can be either Bridge Tied Load
(BTL) or Single-Ended (SE), the curves of each application
are shown separately.

The BTL application diagram is shown in Fig.4.
The quiescent current has been measured without
any load impedance. The total harmonic distortion
as a function of frequency was measured with a low-pass
filter of 80 kHz. The value of capacitor C2 influences
the behaviour of the SVRR at low frequencies, increasing
the value of C2 increases the performance of the SVRR.
The figure of the mode select voltage (V
of the supply voltage shows three areas; operating, mute
and standby. It shows, that the DC-switching levels
of the mute and standby respectively depends
on the supply voltage level.

The SE application diagram is shown in Fig.14.
The capacitor value of C3 in combination with the load
impedance determines the low frequency behaviour.
The total harmonic distortion as a function of frequency
was measured with low-pass filter of 80 kHz. The value
of capacitor C2 influences the behaviour of the SVRR
at low frequencies, increasing the value of C2 increases
the performance of the SVRR.
General remark
The frequency characteristic can be adapted
by connecting a small capacitor across the feedback
resistor. To improve the immunity of HF radiation in radio
circuit applications, a small capacitor can be connected
in parallel with the feedback resistor; this creates a
low-pass filter.
