Load Disconnect for the TPS6510x and TPS6514x
Texas InstrumentsMany boost converters have an external rectifier diode. The input voltage of the TPS6510x and TPS6514x main boost converter is connected to the output voltage when the device is disabled. Due to the d
CC112x/CC120x RX Sniff mode with Smart Preamble
Texas InstrumentsThis application report shows an innovative way to use the DualSync functionality of the CC112x/CC120x to handle a new kind of preamble. By using what is called SmartPreamble the receiver is able to reliably detect exactly where it woke up in the preamble and use the eWOR timer to go back to sleep and then wake up right before the sync word.
DMA for eXpressDSP-Compliant Algorithm Producers and Consumers
Texas InstrumentsThis application note provides an overview of the DMA architecture specified by the TMS320 DSP Algorithm Standard (also known as XDAIS). It also describes two sets of APIs used for accessing DMA resources: the IDMA2 abstract interface and the ACPY2 library. In addition to providing an overview of fundamental DMA abstractions for eXpressDSP-compliant algorithms this application note highlight

Stabilizing difference amplifiers for headphone applications
Texas InstrumentsThe recent increase in popularity of high-fidelity headphones and lossless audio formats has caused many manufacturers of personal electronics to add high-quality audio outputs to their devices. As a result, 24-bit/192-kHz audio digital-to-analog converters (DACs), once reserved for home highfidelity systems, are now being incorporated into mobile devices such as cell phones, tablets, and portable music players. These DACs deliver extremely low-distortion signals, but are unable to drive headphones directly. To take full advantage of these high-performance parts, a well-designed headphone amplifier must also be added to the system.
