LRCIN
DIN
Sample Rate Clock Input. Controls the update rate (fs).
Serial Data Input. MSB first, right justified (Sony format)
or I

S (Philips). Contains a frame of 16- or 18-bit data.
Bit Clock Input. Clocks in the data present on DIN input.

BCKIN
Mode Control and Clock Signals
1
XTI
Oscillator Input (External Clock Input). For an internal
clock, tie XTI to one side of the crystal oscillator. For an
external clock, tie XTI to the output of the chosen
external clock.
Operation Mode Select. For Software Mode, tie Mode
“HIGH”. For Hardware Mode, tie Mode “LOW”.
Mode Control for Data Input or De-emphasis. When
“HIGH” MD is selected, and a “LOW” selects DM0.
Mode Control for BCKIN or De-emphasis. When “HIGH”,
MC is selected, and a “LOW” selects DM1.
Mode Control for Strobe Clock or Mute. When “HIGH”,
ML is selected, and a “LOW” selects mute.
Buffered Output of Oscillator. Equivalent to XTI.
Oscillator Output. When using the internal clock, tie to
the opposite side (from pin 1) of the crystal oscillator.
When using an external clock, leave XTO open.

ZERO
Infinite Zero Detection Flag, open drain output. When
the zero detection feature is muting the output, ZERO
is “LOW”. When non-zero input data is present, ZERO
is in a high impedance state. When the input data is
continuously zero for 65.536 BCKIN cycles, zero will be
low.
Resets DAC operation with an active “LOW” pulse.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
