Description

GND Digital ground

I External Master Clock Input.

I I2C clock input.

I/O I2C DATA bus. Open drain ouput. Externally this pin should tie to a 680 ohm pull

up resistor.

O Test fs reference pin. For test vector verification. For normal operation this pin

must be tied to ‘0’.

I Active low power down reset. When low, the chip is reset and all programmable

registers are reset to default values. Must activate this pin if the P/S or

ADDR[1:0] change state.

O Analog left channel output 3

O Analog right channel output 3.

O Analog left channel output 2.

O Analog right channel output 2.

O Analog left channel output 1.

O Analog right channel output 1.

GND Analog circuits ground

Common voltage output pin for the DAC.

+5V Analog circuits power supply

Common voltage output pin for the ADC.

GND Analog circuits ground

I ADC right cahnnel input. 1 volt rms input.

I ADC left channel input. 1 volt rms input.

No connection, should be tied to AVSS
