NOTES: (1) Pins 7, 8, 17 and 18: RST, ML, MD, MC for the PCM3002; PDAD, PDDA, DEM1, DEM0 for PCM3003 (Schmitt-Trigger input with 100kΩ typical internal
pull-down resistor). (2) Pins 9, 10, 11, 15: SYSCLK, LRCIN, BCKIN, DIN (Schmitt Trigger input). (3) Pin16: 20BIT for PCM3003 (Schmitt-Trigger input, 100kΩ
typical internal pull-down resistor). (4) Pin 12: DOUT. (5) Pin 16: ZFLG (open drain output). (6) High Pass Filter for Offset Cancel. (7) Refer to Application Bulletin
AB-148 for information relating to operation at lower sampling frequencies. (8) fIN = 1kHz, using Audio Precision System II, rms mode with 20kHz LPF, 400Hz
HPF used for performance calculation. (9) fOUT = 1kHz, using Audio Precision System II, rms mode with 20kHz LPF, 400Hz HPF used for performance calculation.
(10) Applies for voltages between 2.4V to 2.7V for 0°C to +70°C and 256fS/512fS operation (384fS not available). (11) SYSCLK, BCKIN, and LRCIN are stopped.
