Terminal Functions

TERMINAL

I/O

DESCRIPTION

NAME

NO.

I/O

DESCRIPTION

AGND1

18

I

Analog ground for sigma-delta DAC

AGND2

45

I

Analog ground for analog audio output drivers

AGND3

52

I

Analog ground for bandgap reference

AUDIO LEFT

35

O

Left channel line-level analog audio output. The AUDIO LEFT output driver

provides line level signals (1 Vrms max) for line output. The AUDIO LEFT

output is capable of driving a 600-

Ω load.

AUDIO MONO

39

O

Monaural variable line-level analog audio output. The AUDIO MONO output

signal is the sum of the AUDIO RIGHT and AUDIO LEFT outputs divided by

2. The output is capable of driving a 10-k

Ω load.

AUDIO RIGHT

38

O

Right channel variable line-level analog audio output. The AUDIO RIGHT

output driver provides line level signals (1 Vrms max) for line output. The

AUDIO RIGHT output is capable of driving a 600-

Ω load.

AUX AUDIO1L

21

I

Left channel auxiliary analog audio input 1

AUX AUDIO1R

23

I

Right channel auxiliary analog audio input 1

AUX AUDIO2M

24

I

Mono channel auxiliary analog audio input 2

ABCLK

12

I/O

Auxiliary serial bit clock input. The ABCLK bit clock signal clocks the serial

PCM data (ASDATA) into the TLC320AD80.

ALRCLK

13

I/O

Auxiliary left/right channel indicator. ALRCLK signifies whether the serial

PCM data is associated with the left channel DAC or the right channel DAC.

ASDATA

11

I

Auxiliary serial PCM data input port. ASDATA can be configured as 16 or 18

bits with the most significant bit (MSB) first, 2’s complement format.

AVDD1

14

I

Analog 5-V power supply for the sigma-delta DAC

AVDD2

44

I

Analog 5-V power supply for the analog audio output drivers

AVDD3

50

I

Analog 5-V power supply for the bandgap reference

BCLK

9

I

Serial bit clock input. BCLK clocks the serial PCM data (SDATA) into the

device.

BGFLTR

46

I

Bandgap reference filter. BGFLTR provides for noise filtering of the internal

bandgap reference (2.25 V). BGFLTR requires a 0.1

µF capacitor to analog

ground. This voltage node should be loaded only with a high-impedance dc

load.

CDIN

61

I

SPI bus serial control data input. Data is transferred MSB first. CDIN

specifies the channel specific attenuation and mute, serial PCM data format

and rates, de-emphasis mode, audio input port selection, and stereo or

monaural analog inputs.

CDOUT

62

O

SPI bus serial control data output port

CS

59

I

SPI bus chip select input (active low)

DGND1

6

I

Digital ground for the sigma-delta DAC

DGND2

58

I

Digital ground for the serial interface

DVDD1

5

I

Digital 5-V power supply for the sigma-delta DAC

DVDD2

57

I

Digital 5-V power supply for the serial interface

EXT INL

26

I

Left channel external analog audio input

EXT INR

27

I

Right channel external analog audio input
