To achieve reliable power amplifier designs you must consider the stress on the amplifier compared to its power handling limitations. Power handling limits are specified by the Safe Operating Area (SOA) curves of the power amp. Stress on the amplifier depends on amplifier load and signal conditions which can be evaluated with straightforward techniques.
The industry is imposing increasingly aggressive testability requirements on modern electronics development. Existing designs require additional hardware modifications to provide all the testability functions. The JTAG/IEEE 1149.1 specification for 4-wire test bus interfaces or boundary-scan architecture provides a standard for built in testability functions. This document discusses the reliabilit
This document describes the design changes from the bq27541 (firmware version 1.12) to bq27541-v200 (firmware version 2.00). For ordering information and data sheet see the Texas Instruments Web site.
This document discusses special precautions that need to be taken when working with the TMS320C40 emulator. There are several potential problem situations:? The debugger will break any pending CPU/DMA access that is not completed within the time-out period. ? Comm port logic stops when the emulator is halting the device (in a breakpoint or between single steps). (However you can still wor
This application report gives an example of using the bq24650 charge management device to provide a high-efficiency switching-mode charging solution for the LiFePO4 battery.
This application report presents an efficient and precise method on how to achieve the desired resonant frequency of configuring the trim array with only a few iterations and measuring the resonant frequency. First the minimum and maximum resonant frequency is measured; from this data a capacitance gradient is derived which allows a good prediction of the required capacitance. The calculated cap
The PCM9211 evaluation module (EVM) is designed to allow users to record and play back audio signals via a USB interface while running CodecControl software on a PC. The USB interface uses the TAS1020B USB interface device. This document presents a detailed description of the recording interface setup from an analog input to PC and discusses how to play back a digital signal from the PC via a USB

This report presents a fundamental understanding on the theory of low-dropout voltage regulators using a PMOS FET as the pass element to adjust the output current to the load requirements.
This application report builds up an I2C port from two pins in a McBSP, develops the I2C software driver, and interfaces with the voice-band codec(s), including TLV320AIC1103/1109 /1110, TLV320AIC12/
This document contains information on how to interface the TMS320DM642 to a CMOS Digital Image Sensor in raw capture mode. A complete example is shown including hardware and software interfaces. The software consists of a set of routines that are compatible with the Video Port Mini-Driver and External Device Control interface. The discussed interface is proven and has been tested from 320x240 at
