    В® ADS ADS7825 782 5 ADS 782 5 www.burr-brown.com/databook/ADS7825.html 4 Channel, 16-Bit Sampling CMOS A/D Converter
    FEATURES DESCRIPTION в—Џ 25Вµs max SAMPLING AND CONVERSION
    в—Џ SINGLE +5V SUPPLY OPERATION The ADS7825 can acquire and convert 16 bits to
    within В±2.0 LSB in 25Вµs max while consuming only
    50mW max. Laser-trimmed scaling resistors provide
    the standard industrial В±10V input range and channelto-channel matching of В±0.1%. The ADS7825 is a
    low-power 16-bit sampling A/D with a four channel
    input multiplexer, S/H, clock, reference, and a
    parallel/serial microprocessor interface. It can be configured in a continuous conversion mode to sequentially digitize all four channels. The 28-pin ADS7825
    is available in a plastic 0.3" DIP and in a SOIC, both
    fully specified for operation over the industrial –40°C
    to +85В°C range. в—Џ PIN-COMPATIBLE WITH 12-BIT ADS7824

    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.
