    A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)
    This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (О”ОЈ), successive approximation register (SAR), and pipeline analog-to-digital (A/D) converter specifications and performance characteristics. Although there is a considerable amount of detail in this document, the product data sheet for a particular product specification is the best and final reference.

    Interleaving Analog-to-Digital Converters
    It is tempting when pushing the limits of analog-to-digital conversion to consider interleaving two or more converters to increase the sample rate. However, such designs must take into consideration several possible sources of error.

    Interfacing the MSOP8EVM to TMS320C6x Processors
    The modular MSOP8EVM is an evaluation module for single-channel, low-power, 8 to 16-bit serial analog-to-digital converters. This application note presents a method for interfacing this EVM to the TMS320C6x Series DSKs using a 5-6K Interface Board. The EVM software provides compile options to choose the proper data formatting for the ADS7816, ADS7817, ADS7818, ADS7822, ADS7826, ADS7829, ADS7835, A

    Short Cycling the 8-Pin ADS78xx Family
    The most recent 8-pin, 12-bit A/D converters that Burr-Brown has introduced to the market are advertised as high speed, micropower, low priced sampling SAR devices. During product development and the initial introduction period, the engineering effort was placed on optimizing the combination of 12 bits with high speed, low power and low cost. Burr-Brown Applications has revisited these converters

    Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
    This application report analyzes a simple method for calculating minimum acquisition times for successive-approximation register analog-to-digital converters (SAR ADCs). The input structure of the ADC is examined along with the driving circuit. The voltage on the sampling capacitor is then determined for the case when a step function is applied to the input of the driving circuit. Three different

    What Designers Should Know About Data Converter Drift
    Exactly how inaccurate will a change in temperature make an analog-to-digital or digital-to-analog converter? As designers are well aware, a 12-bit device may provide a much lower accuracy at its operating-temperature extremes, perhaps only to 9 or even 8 bits. But for lack of more precise knowledge, many play it safe (and expensive) and overspecify.

    Interfacing the ADS7822 to synchronous serial port of the 80x51 Microcontroller
    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
