Differences between the LC83025E and the LC83026E
Parameter
LC83025E
LC83026E
Decimation filter improved
Input comparator improved
A/D converter block
*
: The V
REF
pin was added in association with the improvements to the input comparator. The V
REF
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.

×
oversampling filters used
Third-order noise shaping
D/A converter block
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.
The LRCKI and BCKI pins must be connected to either
V
DD
or V
SS
; they do not need to be connected to the
LRCKO and BCKO pins.
