Terminal Functions
TERMINAL

DESCRIPTION
NAME
NO.
I/O
DESCRIPTION
AnaPD
6
I
Analog power-down mode. The analog power-down mode disables the analog
modulators. The single-bit modulator outputs become invalid, which renders the
outputs of the digital filters invalid. When AnaPD is pulled low, normal operation of the
device resumes.
AVDD
4
I
Analog supply voltage
AVSS
5
I
Analog ground
CMODE
12
I
Clock mode. CMODE selects between two methods of determining the master clock
frequency. When CMODE is high, the master clock input is 384
× the conversion
frequency. When CMODE is low, the master clock input is 256
× the conversion
frequency.
DOUT
16
O
Data output. DOUT transmits the sigma-delta audio analog-to-digital converter (ADC)
output data to a digital signal processor (DSP) serial port or other compatible serial
interface and is synchronized to SCLK. DOUT is low when DigPD is high.
DVDD
18
I
Digital supply voltage
