Not used on the AD1845.
Not used on the AD1845.
Power Down Signal. Active LO places the AD1845 in its lowest power consumption
mode. All sections of the AD1845, including the digital interface, are shut down and
consume minimal power.
Host Interrupt Pin. A host interrupt is generated to notify the host that a specified
event has occurred.
External Control. These signals reflect the current status of register bits inside the
AD1845. They can be used for signaling or to control external logic.
Reset. Active LO resets all digital registers and filters, and resets all analog filters. Active
LO places the AD1845 in the lowest power consumption mode. XTAL1 is required to be
running during the minimum low pulsewidth of the reset signal.
Voltage Reference. Nominal 2.25 volt reference available for dc-coupling and level-
shifting. V
should not be used to sink or source current.
REF
Voltage Reference Filter. Voltage reference filter point for external bypassing only.
Left Channel Filter. This pin requires a 1.0 F capacitor to analog ground for proper
operation.
Right Channel Filter. This pin requires a 1.0 F capacitor to analog ground for proper
operation.
No Connect.
