AN-521 Dual Tone Multiple Frequency (DTMF)
Texas InstrumentsThe DTMF (Dual Tone Multiple Frequency) application is associated with digital telephony, and provides two selected output frequencies (one high band, one low band) for a duration of 100 ms. A benchmark subroutine has been written for the COP820C/840C microcontrollers, and is outlined in detail in this application note. This DTMF subroutine takes 110 bytes of COP820C/840C code, consisting of 78 bytes of program code and 32 bytes of ROM table. The timings in this DTMF subroutine are based on a 20 MHz COP820C/840C clock, giving an instruction cycle time of 1 ms.
Upgrading to DSP/BIOS II
Texas InstrumentsDSP/BIOS II adds numerous functions to the DSP/BIOS kernel while maintaining 100% Application Programming Interface (API) compatibility with DSP/BIOS I. In addition new functionality has been added to Code Composer Studio?. This application note describes the transition from DSP/BIOS I to DSP/BIOS II and focuses on the enhancements and changes to existing DSP/BIOS I functions.
How to Design an LED Driver Using the TPS92510 (Rev. A)
Texas InstrumentsThis design example consists of a single string of ten LEDs driven with 1-A forward current. This design example is a supplement to the TPS92510 data sheet and provides step-by-step instructions for optimizing an LED driver design. In particular, detailed attention is given to compensating and measuring the feedback loop, implementing the thermal foldback protection, and designing the printed-circuit board layout. Graphs are provided showing the design example test data.
Softstart Using Constant Current Constant Voltage Approach
Texas InstrumentsIn many systems backup power is provided either by batteries or simply by a large value capacitor. Inthese applications the capacitor would only provide the current when the primary power source fails.Further these applications are usually for light load currents. During normal operation the backupcapacitors are kept charged up by a DC/DC converter. The challenge involved in an application
