Step-up Charge Pump Cap Positive/Negative Nodes (Output) - Positive and Negative nodes for the
step-up charge pump’s flying capacitor.
VCP 6
Charge Pump and Digital Core Logic Power (Input) - Positive power supply for the step-up and invert-
ing charge pumps as well as the digital core logic sections.
VFILT+ 8
Step-up Charge Pump Filter Connection (Output) - Power supply from the step-up charge pump that
provides the positive rail for the output amplifiers

Analog Outputs (Output) - The full-scale analog line output level is specified in the Analog Characteris-
tics table.
AOUT_REF 14
Pseudo Diff. Analog Output Reference (Input) - Ground reference for the analog output amplifiers.
This pin must be at the same nominal DC voltage as the AGND pin.
AGND 16 Analog Ground (Input) - Ground reference for the low voltage analog section.

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 V
off
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 V
RMS
Select (Input) - Selects the analog output full-scale voltage. Setting this pin low (GND)
selects 1 V
RMS
, while setting it high (VL) selects 2 V
RMS
.
DEM 21
De-emphasis (Input) - Selects the standard 50 μs/15 μs digital de-emphasis filter response for 44.1 kHz
sample rates when enabled.
I²S
/LJ 22
Digital Interface Format (Input) - Selects the serial audio interface format. Setting this pin low (GND)
selects I²S, 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.

2. CHARACTERISTICS AND SPECIFICATIONS
RECOMMENDED OPERATING CONDITIONS
AGND = DNGD = CPGND = 0 V; all voltages with respect to ground.
Notes: 1. VCP and VA must be supplied with the same nominal voltage. Additional current draw will occur if the sup-
ply voltages applied to VCP and VA differ by more than 0.5 V.
ABSOLUTE MAXIMUM RATINGS
AGND = DNGD = CPGND = 0 V; all voltages with respect to ground.
WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation
is not guaranteed at these extremes.
