Sample Application Circuit
LA9410
Technical information
1. Internal digital input filter
The filter internal to the LA9410 is designed to form a third-order filter when used in combination with an
external first-order filter. Characteristics when used alone and when used in conjunction with the external filter
are illustrated below.
2. External components for input circuit for 1-bit DAC
The LA9410 circuit is directly connected from the input to line output. If the differential of the external
components used for the input circuit (differential input) of the 1-bit DAC is large, it will become a DC offset,
and may cause popping noise during selection and muting.
