SI-ENTechnology, the industry's leading professional analog and mixed-signal semiconductor manufacturer, today announced the launch of a led dot matrix driver chip, the SN3728, with a music equalizer display and synchronized music. The chip has built-in ADC, memory register and intelligent digital signal processing module. It adopts self-scanning mode, which can synchronously display the energy column effect of each band of music equalizer and support the effect of arbitrary picture programming breathing or music synchronous breathing without external software real-time processing. .
The SN3728 can be configured with I2C bitmaps in the form of 5x11, 6x10, 7x9, 8x8, etc. SN3728's LED dot matrix driver solution can add personalized elements to portable products, making products more attractive to consumers, thereby enhancing the competitiveness of products.
The SN3728 has the following main features:
1. Configure the dot matrix to be 5x11, 6x10, 7x9, 8x8
2. Built-in self-scanning, no external software processing required
3. Synchronous LED dot matrix display energy band effect of each band of music equalizer
4. Any screen bright and dark programming breathing or synchronized breathing with music
5. I2C interface control
6. The audio amplification gain can be set internally, and the scan current size can be configured.
Typical application circuit diagram:
The SN3728 operates from 2.7V to 5.5V and integrates over-temperature protection. The operating temperature range is -40°C to +85°C. It is available in a slim QFN24 package and is available in volume. .
