AN-336 Understanding Integrated Circuit Package Power Capabilities (Rev. A)
Texas InstrumentsThe short and long term reliability of National Semiconductor's interface circuits like any integrated circuit is very dependent on its environmental condition. Beyond the mechanical/environmental factors nothing has a greater influence on this reliability than the electrical and thermal stress seen by the integrated circuit. Both of these stress issues are specifically addressed on every inter
Interfacing the TLV1544 Analog-to-Digital Converter to the TMS320C50 DSP (Rev. A)
Texas InstrumentsThis application report presents two hardware solutions for interfacing the TLV1544 10-bit low-power analog-to-digital converter (ADC) to the TMS320C50 16-bit fixed-point digital signal processor (DSP).
