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 thermal resistance = 100 K/W for the DIP8 envelope;
the maximum sine wave power dissipation for

For T

The BTL application diagram is shown in Fig.3.
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
ms
) as a function
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.13.
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 (56 k
); this creates a
low-pass filter.
