U-100A UC3842/3/4/5 Provides Low-Cost Current-Mode Control
Texas InstrumentsThe fundamental challenge of power supply design is to realize simultaneously two conflicting objectives: good electrical performance and low cost. The UC3842/3/4/5 control ICs are integrated pulse-width modulators (PWMs). These inexpensive IC controllers provide all the performance advantages of current-mode operation. In addition the UC3842 series is optimized for efficient power-sequencing of
bq2083 and bq2085 Board Offset Characterization and Compensation
Texas InstrumentsThe bq208x (bq2083 bq2084 and bq2085) products are high-precision advanced gas gauge products for battery monitoring and management. Because the current signal ismeasured through a small sense resistor (< 20 m?? to minimize power loss compensation for the ADC input offset is critical for the accuracy of the measurement. This application note discusses common issues associated with board offse
Clock Fail Detection for Stellaris LM3SX00 MCUs (AN01278)
Texas InstrumentsThe Stellaris® on-chip clock failure detection circuitry allows a microcontroller to respond appropriately if the main crystal oscillator stops functioning. This capability can be extended to situations in which the crystal oscillator fails due to an open or short circuit.
Transmission of Still and Moving Images Over Narrowband Channels
Texas InstrumentsRadio networks such as those used by emergency services or public transportation transmit across a narrow bandwidth thus requiring low transmission rates. This document describes the channels and transmission method of these existing networks. Applying complex algorithms to code images allows development of a source codec. This codec uses multiple TMS320C40 32-bit parallel digital signal proces
ADS7809 Tag Features
Texas InstrumentsThe ADS7809 is part of a family of capacitive redistribution SAR A/D converters that feature a serial output and a tag pin for cascading multiple converters. Other members of this family include the ADS7806 ADS7807 ADS7808 ADS7824 and ADS7825. Note that the even numbered converters are 12-bit converters and the odd numbered converters are 16-bit converters.

Compatibility Considerations: TMS570LS20x/10x to TMS570LS31x/21x (Rev. A)
Texas InstrumentsThis application report provides a summary of the main changes required for porting an application written on the Hercules™ TMS570LS20x/10x series of microcontrollers over to the Hercules TMS570LS31x/21x series of microcontrollers. A brief description of the process technology differences is also included.
AN-2001 Daisy Chaining Precision DACs (Rev. A)
Texas InstrumentsIt is not uncommon for the system designer to face a quagmire of reconciling the system complexity withthe desire to keep the system footprint small. One specific example that often arises in the context ofsmall system footprint is the need for single master controller to communicate with a number of slavedevices. This is not much of a problem if the master controller has multiple I/O resour
