3 VINR+ input Right channel noninverting differential analog input, 2.8VPP nominal full-scale.
4 VCC1 power_in Analog supply, +4.0V nominal.
5 AGND power_in Analog ground.
6 AGND power_in Analog ground.
7 AGND power_in Analog ground.
8 AGND power_in Analog ground.
9 VCC2 power_in Analog supply, +4.0V nominal.
10 VINL- input Left channel inverting differential analog input, 2.8VPP nominal full-scale.
11 VINL+ input Left channel noninverting differential analog input, 2.8VPP nominal full-scale.
12 AGND power_in Analog ground.
13 VCOML output Left channel common-mode voltage, nominally 0.4875 × VCC2.
14 REFGNDL power_in Left channel reference ground; connect to analog ground.
15 VREFL output Left channel reference output, for decoupling purposes only.
16 PCMEN input PCM output enable, active high.
17 HPFDR input Right channel high-pass filter disable, active high.
18 HPFDL input Left channel high-pass filter disable, active high.
19 FS0 input Sampling mode select with FS1: 00 = Normal mode, 10 = Double Speed mode, 01 = Quad Speed mode, 11 = Reserved.
20 FS1 input Sampling mode select with FS0: 00 = Normal mode, 10 = Double Speed mode, 01 = Quad Speed mode, 11 = Reserved.
21 DF input Digital decimation filter response select: DF = 0 gives Classic filter response, DF = 1 gives Low Group Delay response.
22 DGND power_in Digital ground.
23 DGND power_in Digital ground.
24 DGND power_in Digital ground.
25 SUB1 input TDM active sub-frame select with SUB0: 00 = Sub-frame 0, 01 = Sub-frame 1 (SUB0 = 1, SUB1 = 0), 10 = Sub-frame 2, 11 = Sub-frame 3.
26 SUB0 input TDM active sub-frame select with SUB1; see SUB1 for the decoding.
27 NC unconnected No external connection; internally bonded to ESD pad.
