Monolithic IC MM1285
Outline
This IC collects various driver functions used in pagers and other portable communication devices in a single
chip. Recently there have been requests for more compact pagers and portable telephones, and at the same
time new functions and features are being added, leading to a strong demand for miniaturized and hybrid
components. This IC meets these needs through adoption of a miniature package.
The speaker driver incorporates functions for varying audio volume through data, a feature which can be used in
novel applications.
