Analog-to-digital converters can be controlled by a normal I/O port or with the synchronous serial port of the 80x51 microcontrollers. The synchronous serial port is more efficient however there are some pitfalls to be aware of when configuring the 8-pin A/D converters (ADS1286 ADS7816 ADS7817 and ADS7822) from Burr-Brown. This application bulletin describes how to get around these pitfalls an

The INA115 is a precision instrumentation amplifier (IA). Its gain-sense and amplifier output connections are available so that gains can be accurately set using external resistors. By adding switches or a multiplexer you can make a precision programmable-gain IA (PGIA). Using the circuit topology shown in this bulletin the switches are in series with op amp inputs so their resistance does not a

This application report discusses how to design a simple and ultra low-power grip detector BoosterPack for the MSP430 LaunchPad™. The PINOSC feature in every msp430G2xx2 and msp430G2xx3 device makes it possible to eliminate all the external components when implementing a capacitive touch design. All the components used in the grip detector such as capacitive sensors LEDs are all integrate

This application report discusses the Power Budget of an LED backlight driver. It provides experimental and theoretical methods of calculating different losses associated with LED backlight drivers. It also provides an analytical discussion on behavior of different losses vs brightness levels.

C and C++ are very powerful and expressive programming languages. Even so these languages lack the power to express certain programming details that can be critical to achieving good compiler performance on a DSP. The role of Compiler Consultant found in Code Composer Studio™ v3.0 is to recognize such situations inform the developer about what is missing and exactly how to address it. I

In higher end control applications such as servo drives, high-resolution feedback is required to provide precise phase current measurements for low-torque ripple and precision positioning; however, f

Interfacing DRA7xx Audio to Analog Codecs

DSP Library (DSPLIB) is a collection of optimized C55x assembly functions that implement a wide variety of DSP functions. The TMS320C55x DSP Library Programmer’s Reference User's Guide provides cycle estimation for the execution of each function in the library. This work enables the user to measure the performances of a sub-set of the DSPLIB functions executed on real hardware and with some addit
