Sound to Your Next Design!
Play voice prompts, polyphonic audio alerts, and sound effects from a library of up to 4096 custom, pre-recorded audio phrases with just a few simple serial commands.
Integrated Class-D outputs directly drive a 0.25W speaker without an external amplifier or low-pass filter. The KX1400 Audio Playback IC makes it easy to add audio to your design.
Roll Your Own Voltage Regulator
Need to generate a 3V supply from a 5V input, but don't have the right LDO handy? Our latest "Application Spotlight" article shows how to build simple, low-cost voltage regulators out of a handful of common components.
Deriving multiple power supplies from a single input is a task common to most embedded systems. In this article, we explore some simple circuits for stepping down a 5 volt rail to 3 volts.
In most cases, the obvious solution is to use a 3 volt LDO − it's a simple integrated solution. However, there are times when using an LDO may not be the best or lowest cost choice.
