CS4353
VA
17
Low Voltage Analog Power (Input) - Positive power supply for the analog section.
VBIAS
18
Positive Voltage Reference (Output) - Positive reference voltage for the internal DAC.
RESET
19
Reset (Input) - Optional connection for an external reset control. The device enters a powered-down
state when this pin is set low (GND) OR when the VCP supply falls below the Voff threshold (see See
“Internal Power-on Reset Threshold Voltages” on page 10.). This pin should be set high (VL) during nor-
mal operation.
1_2VRMS
20
1 or 2 VRMS Select (Input) - Selects the analog output full-scale voltage. Setting this pin low (GND)
selects 1 VRMS, while setting it high (VL) selects 2 VRMS.
DEM
21
De-emphasis (Input) - Selects the standard 50
s/15 s digital de-emphasis filter response for 44.1 kHz
sample rates when enabled.
IS/LJ
22
Digital Interface Format (Input) - Selects the serial audio interface format. Setting this pin low (GND)
selects IS, while setting it high (VL) selects Left-Justified.
LRCK
23
Left / Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial
audio data line.
SDIN
24
Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
Thermal Pad
-
Thermal Relief Pad - This pad may be soldered to the board, however it MUST be electrically isolated
from all board connections.
