Power-Down Signal. Active LO control places AD1846 in its lowest power consump-
tion mode. All sections of the AD1846, including the digital interface, are shut down
and consume minimal power.
Host Interrupt Pin. T his signal is used to notify the host that the DMA Current Count
Register has underflowed.
External Control. T hese signals reflect the current status of register bits inside the
AD1846. T hey can be used for signaling or to control external logic. X LT L1 and
X LT L0 are open-drain outputs.
Voltage Reference. Nominal 2.25 volt reference available externally for dc-coupling and
level-shifting. V
REF
should not be used where it will sink or source current.
Voltage Reference Filter. Voltage reference filter point for external bypassing only.
Left Channel Filter Input. T his pin requires a 1.0
μ
F capacitor to analog ground for
proper operation.
Right Channel Filter Input. T his pin requires a 1.0
μ
F capacitor to analog ground for
proper operation.
No Connect. Do not connect.
