Functional Block Diagram of Loop thru
This results in a flat frequency response from the mixer input to the IF amplifier output
and allows tuner alignment without the need of an external resistor.

ADC
1)
A built-in 5 level Analog to Digital converter is available on P4/ADC pin. This converter
can be used to read out an external AFC information via the I2C-BUS interface. The
relationship between the external voltage at P4/ADC pin and the bits A2, A1 and A0 is
given in Table 14. P4 output port cannot be used and the corresponding bit needs to be
programmed to logic 0 when the ADC is in use.
1) ADC function is only available in TUA 6039F-2.
