    Using the Continuos Parallel Mode with the ADS7824 and ADS7825
    The ADS7824 and ADS7825 are 12-bit and 16-bit converters that have a four channel multiplexed front end. The channel selection on the analog input of these converters is programmable by way of the pins on the devices, A0 and A1. This feature provides the most flexibility by allowing the user to change to the preferred input channel on the fly. Additionally, the input channels can be cycled by util

    ADS7809 Tag Features
    The 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.

    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

    Determining Minimum Acquisition Times for SAR ADCs, part 2
    The input structure circuit of a successive-approximation register analog-to-digital converter (SAR ADC) incombination with the driving circuit forms a transfer function that can be used to determine minimum acquisition times for different types of applied input signals. This application report, which builds on Determining Minimum Acquisition Times for SAR ADCs When a Step Function is Applied to

    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.

    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.
