Figure 28. Internal stereoblend characteristics

TDA7402

The gain can be programmed through 4 bits in the ”Stereodecoder-Adjustment”-byte. All necessary internal ref-

erence voltages like REF5V are derived from a bandgap circuit. Therefore they have a temperature coefficient

near zero.

3.9 Highcut Control

The highcut control set-up is similar to the stereoblend control set-up : the starting point VHCH can be set with

2 bits to be 42, 50, 58 or 66% of REF5V whereas the range can be set to be 17, 22, 28 or 33% of VHCH (see

fig. 30).
