Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient (89% efficient when...
Stereo 2.8W Class D Audio Amplifier - I2C Control AGC - TPA2016
A mini class D with AGC and I2C control? Yes please! This incredibly small stereo amplifier is surprisingly powerful. It is able to deliver 2 x 2.8W channels into 4 ohm impedance speakers (@ 10% THD) and it has a i2c control interface as well as an AGC (automatic gain control) system to keep your...
Optomax Digital Liquid Level Sensor
The Optomax is an optical liquid level sensor that detects the presence or absence of almost any liquid — oil or water based. Inside the polysulfone housing, an infrared LED and matching phototransistor work together: when dry, the IR light reflects internally back to the sensor; when the tip is ...
