Dual Output Boost Converter
Texas InstrumentsThe boost converter is modified to provide bipolar 12-V outputs from 5-V supply. Using the UCC3803 to control the basic boost converter building block the -12-V outputs are generated using a coupled inductor and a flying capacitor. Output voltage regulation and efficiencies are compared and presented.

Using Windowing With SNRBoost 3G Technology
Texas InstrumentsCoherency is a well-known requirement when using FFT techniques to examine the spectrum of the output of an analog-to-digital converter. SNRBoost(3G) technology results in loss in coherency and this can be seen as an unstable noise floor in the spectrum. Windowing of the ADC output is a well-known solution to restore coherency and stable spectrum.However windowing also modifies the amplitude o
Migrating from TMS320VC5410 to TMS320VC5416 (Rev. C)
Texas InstrumentsThis document describes issues of interest related to migration from the TMS320VC5410 to the TMS320VC5416. The objective of this document is to indicate differences between the two devices. Functions that are identical between the two devices are not included. For detailed information on the specific functions of either device refer to the device data sheets 5410 (SPRS075) 5416 (SPRS095) the T
C5x EVM Provides for Audio Processing
Texas InstrumentsThe TMS320C5x evaluation module (EVM) has RCA input/output jacks and a TLC32046 Analog Interface Chip (AIC). It offers an easy-to-configure system for audio processing applications. Whether implementing simple delays and echoes or complex multi-filter digital reverberation TMS320C5x EVM features make it easy.
C54x Extended Addressing
Texas InstrumentsIn some applications there is a need to store and have easy access to multiple algorithms. This increases the program memory requirement beyond 64K words. The TMS320LC548 and TMS320LC549 provide direct support for an extended address capability for program memory space. This extended address capability supports a total of 4M 16-bit words if the on-chip RAM (32K words) is mapped to program space a

Simple Circuit Delivers 38Vp-p at 5A from 28V Unipolar Supply
Texas InstrumentsSince the first analog IC requiring bipolar supplies was developed people have been trying to operate them from unipolar supplies. Not only do the headroom (VS - VOUTMAX) requirements come into play but with a unipolar supply typically come unipolar outputs. To get bipolar output swings from a unipolar supply drive the load differentially and create a reference signal wh
