SDTO

O

Serial Data Output Pin

Data bits are presented MSB first, in 2’s complement format.

This pin is “L” in the power-down mode.

10

LRCK

I

Left/Right Channel Select Pin

The fs clock is input to this pin.

11

MCLK

I

Master Clock Input Pin

12

SCLK

I

Serial Data Input Pin

Output data is clocked out on the falling edge of SCLK.

13

PDN

I

Power-Down Pin

When “L”, the circuit is in power-down mode.

The AK5380 should always be reset upon power-up.

Serial Interface Format Pin

“L”: MSB justified, “H”: I

15

TTL

I

Digital Input Level Select Pin

“L”: CMOS level (VD=2.7

∼5.5V), “H”: TTL level (VD=4.5∼5.5V)

16

TST

I

Test Pin (Internal pull-down pin)

This pin should be left open.

Note: All input pins except pull-down pins should not be left floating.
