Digital Microphone Amplifier, Reverberation Board Low Noise for Audio Equipments

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples..
Cond over I2C,The chip can be configured as 4 single-ended input channels, or two differential channels..
As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range..
We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter..
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed , you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs..

Clock Splitter, Electronic Component Stable for Home for Industry

Si5351A clock generator is an I2C controller clock generator. It uses the onboard clock to drive multiple PLLs and clock dividers through I2C instructions. By setting for and divider, you can make precise arbitrary frequencies..
Most importantly, we even provide excellent tutorials and libraries to help you get started! Our is designed to work for microcontrollers and IDEs, but it can be easily ported to your favorite platform through I2C support..
With the breakthrough for Adafruit's Si5351A clock generator, you will never look for another crystal! The chip has an accurate 25MHz crystal reference voltage source and internal for and frequency divider, so it can generate almost any frequency, from 003c8KHz to 150+ MHz..
There are three independent outputs, and each output can have a different frequency. Through a breadboard friendly plug or optional SMA connector, the output is 3Vpp..
Such convenient small chip is put on its own breakout board PCB, with 3.3V LDO regulator, so it can be powered by 3-5VDC. We also placed a level circuit on the I2C line, so you can safely use the chip under 3V or 5V logic..
