Digital Logic Power (Input) - Positive power supply for the digital interface section. Typically

3.0 to 5.0 VDC.

Differential Right Channel Analog Input (Input) - The full scale analog input level (differen-

tial) is specified in the Analog Characteristics specification table and may be AC coupled or DC

coupled into the device, see Figure 12 for optional line input buffer.

Differential Left Channel Analog Input (Input) - The full scale analog input level (differential)

is specified in the Analog Characteristics specification table and may be AC coupled or DC

coupled into the device, see Figure 12 for optional line input buffer.

Analog Power (Input) - Positive power supply for the analog section. Nominally +5 Volts.

Analog Ground (Input) - Analog ground reference.

Differential Right Channel Analog Output (Output) - The full scale analog output level (dif-

ferential) is specified in the Analog Characteristics specification table.

Differential Left Channel Analog Output (Output) - The full scale analog output level (differ-

ential) is specified in the Analog Characteristics specification table.

Reset (Input) - When low, the device enters a low power mode and all internal registers are

reset, including the control port. When high, the control port becomes operational and normal

operation will occur.
