TDA8296

Digital global standard low IF demodulator for analog TV and FM radio

Application hints for DAC supply: it is required to use de-coupling capacitors at

VDDA(DAC1)(3V3) and VDDA(DAC2)(3V3) supplies of > 100nF. A decoupling capacitor at pin

RSET is not allowed. The component RRSET should be placed close to the chip.
