SLES023D December 2001 – December 2016 PCM1802
The PCM1802 requires a 5-V nominal supply and a 3.3-V nominal supply. The 5-V supply is for the analog circuitry powered by the VCC pin. The 3.3-V supply is for the digital circuitry powered by the VDD pin. The decoupling capacitors for the power supplies must be placed close to the device pins.
