A DSP/BIOS AIC23 Codec Device Driver for the TMS320DM642 EVM
Texas InstrumentsThis document describes the usage and design of a device driver for the AIC23 audio codec on the TMS320DM642 EVM. This device driver is written in conformance to the DSP/BIOS™ IOM device driver model and uses the generic TMS320C6x1x EDMA McASP driver to transfer samples to and from the serial port. For details on this generic driver see the application note A DSP/BIOS EDMA McASP Device D
LO Harmonic Effects on TRF3705 Sideband Suppression
Texas InstrumentsThe LO harmonic effects on I/Q errors and sideband suppression (SBS) in the RF modulator was analyzed in application report SLWA059. This application report further investigated LO harmonic effects when attempting to achieve an increased level of SBS performance. The selectivity requirements for the second- and third-order harmonics are outlined to aid in proper filter design. In the measurement

Tips for Using the ADS78xx Family of A/D Converters
Texas InstrumentsThe input to each of the members of the ADS Family (ADS7804/05/06/07/08/09/10/19 so far) is a resistor divider network converting the input signal to the range used internally. This resistor divider offers inherent overvoltage protection which will often simplify analog circuitry.
Applying I2C-Compatible Temperature Sensors in Systems With Slow Clock Edges (Rev. A)
Texas InstrumentsThis Application Note describes a method of interfacing a given microcontroller with a Texas Instruments digital temperature sensor.
Building a Superior Battery Monitor with the bq27x00
Texas InstrumentsThe bq27x00 is a complete gas gauge solution for lithium-ion and lithium-polymer batteries. The bq27x00 also has internal registers and control commands that enable the host to use it as a battery monitor. A battery gas gauge solution can be built one of two ways: ignore all algorithms built into the bq27x00 and use the primitive functions to build a fully customized solution or use some of the h
TFT-LCD Power Supply Using TPS65120 Single Inductor Quadruple-Output Powr Supply
Texas InstrumentsThe reference design and application examples shown in this document help design a TFT-LCD power supply as well as show implementations of power-down sequencing programmable sequencing and boosting output current.
TMS320C6201 (Revision 2.x) to TMS320C6201B (Revision 3.X) (Rev. A)
Texas InstrumentsSamples of the Texas Instruments (TI™) TMS320C6201B DSP will be available in the second half of 1998 with volume production starting at the end of the year. The TMS320C6201B revision is manufactured using a 0.18-micron process compared to the currently available revision 2 that uses a 0.25-micron process. The use of a smaller process for the TMS320C6201B DSP will lead to significantly lower
General Guidelines: CDC7005 as a Clock Synthesizer and Jitter Cleaner
Texas InstrumentsThis application report is a general guide for using the CDC7005 clock synchronizer/synthesizer and jitter cleaner from Texas Instruments. This report explains the basic functionality and methods for using the device efficiently along with the results of evaluations. It also describes the clock termination method decoupling the power supply and general applications.
