PCM3501

SPECIFICATIONS

All specifications at TA = +25°C, VDD = VCC = 3.3V, fS = 8kHz, and nominal system clock (XTI) = 512fS, and differntial input and output mode, unless otherwise noted.

Measurement band is 100Hz to 0.425fS.

NOTES: (1) Pins 6, 7, 8, 9, 10, 15, 17, 18, 19, 20 (M/S, TSC, BCK, FS, DIN, SCKIO, XTI, HPFD, LOOP, PDWN). (2) Pins 8, 9, 10, 15, 17 (BCK, FS, DIN, SCKIO,

XTI (Schmitt-Trigger input). (3) Pins 6, 7, 18, 19, 20 (M/S, TSC, HPFD, LOOP, PDWN; (Schmitt-Trigger input with internal pull-down). (4) Pins 8, 9, 11, 12, 15,

16 (BCK, FS, DOUT, FSO, SCKIO, XTO). (5) If VCOM load impedance (RCOM) is lower than 100kΩ, the user needs to connect external resistors to AGND and

VCC with resistance of RCOM/10 or lower. (6) fIN = 1kHz, Audio Precision System II, RMS mode with 3.4kHz LPF, 100Hz HPF.
