Description
The M61510AFP is a digital sound controller IC which is ideal for home audio applications. M61510AFP includes
five-input selector, input volume control, surround sound (effect switchable in three stages), tone control (3 bands),
loudness, and two-channel master volume control, all controllable via serial data. The M61510AFP can be interfaced
with external circuits even when using the internal surround sound. And a common data format (software-compatible)
facilitates M61510AFP substitution.
