10.12 SW2/AGC (Pin 11)
10.13 Test Mode
4528N–AUDR–11/09
The pin SW2/AGC works as a switching output (open drain, pin 11) or as an AM AGC-control pin
to control the cascade stage of an external AM-preamplifier.
The SW2/AGC is controlled by bits 47 and 48 as given in
Table 10-15. Switching Output 2/AGC Mode
Note:
Figure 10-2. Internal Components at SW2/AGC
A special test mode is implemented for final production test only. This mode is activated by set-
ting bit 123 = 1. This mode is not intended to be used by customer application. For normal
operation bit 123 has to be set to 0.
Table 10-16. Test Mode
In AGC mode, the output voltage is 6V down to 1V.
