This application note covers thermal response considerations for sensors that come in a DSBGA package for measuring skin temperature for applications such as wearables such as fitness bands and medical devices.

It will specifically focus on the LMT70, a 0.88mm x 0.88m 0.13°C max accuracy (0.05°C typ) temp sensor over the human body temperature range, but learning can be applied to other temperature sensors that come in a similar package, whether they be analog or digital sensors. Contact temperature sensors, such as the LMT70, need to be placed in close contact with the surface that needs to be measured.

This can be quite challenging for the DSBGA package that is if fast thermal response is also necessary. Experimental results of different PCB layouts will be presented when measuring axillary.

This design note provides information concerning the designing of TIA/EIA-644 interface circuits. The TIA/EIA-644 standard is discussed including electrical characteristics interconnections line termination and noise immunity. Finally eye patterns are used to measure the effects of signal distortion noise signal attenuation and the resultant intersymbol interference (ISI) in a data transmis

Today's voltage regulator modules (VRMs) employ off-line SMPS techniques. Traditionally they are usually discarded when they fail because they are so challenging to debug and so inexpensive to replace. Investigation of these failed modules reveals some common failure modes. Some failures are caused by other systems' passive components that fail after repeated electrical stress. Recognizing these

This paper discusses a method by which the Texas Instruments (TI)(tm) TMS320C62xx or C62xx high performance fixed point DSPs overcome the traditional advantage held by floating point DSPs -- precision and speed.Using the Radix-4 Fast Fourier Transform (FFT) this document illustrates how extended precision arithmetic multiplication in particular can be performed on the 'C62xx. Using the te

In many TMS470R1x applications direct memory access (DMA) is used to move data between the system memory and peripherals to communicate with external devices. When the external device detects a data error a request (normally an interrupt) will be sent to the TMS470 to restart the unfinished DMA block transfer. This application note presents a generic software approach to restarting the DMA chan
