*: The VREF pin was added in association with the improvements to the input comparator. The VREF pin external

capacitor must be located as close as possible to the LC83026E, and must be connected with lines that are as

short as possible.

D/A converter block

Second-order noise shaping

Third-order noise shaping

Single-pin output used.

Two-pin output operation

Reset time

One or more sampling period

Two or more sampling periods

When no digital input is provided The LRCKI and BCKI pins must be connected to the

(when the SELC pin is low)

LRCKO and BCKO pins.
