Current limit in an LDO is defined by establishing an upper boundary for the current supplied. Unlike a constant current source, LDOs supply current on demand but can also control the total power regulated. Current limiting is achieved through internal circuitry controlling the output stage transistors inside the LDO. Source: Texas Instruments   This is a classic current-limit circuit for an LDO and is commonly referred to as a “brick-wall” current limit due to its abrupt c ...
A smart microphone integrates a traditional microphone with ultra-low-power digital signal processing technology for extracting command information from a human voice. When an application only needs a small set of commands, the DSP capability within the smart microphone can do all the computing locally without waking up the main system or connecting to a server. This capability is the key to interfacing with the human voice interface in smart appliances, TVs, robots and other digital assistants ...
There's a couple things you might not know about Bluetooth 5 worth knowing:   Data transfer rate up to 2Mbps Twice as fast is Bluetooth 4.2 and 5 times faster than Bluetooth 4.0 High-speed or long-range modes for increased flexibility   Because the data transfer rate can go as high as 2Mbps, you can develop applications using voice, audio, imaging, and data logging that were not previously an option using Bluetooth low energy.   To learn more, check out this article.   ...
What's so interesting about the DAC8775? Well let me tell you:   The DAC8775 is a quad-channel precision, fully integrated, 16-bit, digital-to-analog converter (DAC) with adaptive power management, and is designed to meet the requirements of industrial control applications.The adaptive power management circuit, when enabled, minimizes the power dissipation of the chip.   When programmed as a current output, the supply voltage on the current output driver is regulated between 4.5 V an ...
For anyone who has had to slug their way through technical documentation, let me tell you that it can be a difficult experience in learning patience. But sometimes you have to put in the time if it has good information that you need to do your job.   If not datasheets or user manuals, what other choices do you have to get the information you need, especially when a design project is nearing the deadline? Dust off those big thick engineering textbooks you bought (or took a loan to buy) when ...
