    в—Џ The ADS7817 is a 12-bit, 200kHz sampling Analog-toDigital (A/D) converter that features a high impedance fully
    differential analog input. The reference voltage can be varied from 100mV to 2.5V, with a corresponding inputreferred resolution between 49ВµV and 1.22mV.
    The differential input, low power, automatic power down,
    and small size make the ADS7817 ideal for direct connection to transducers in battery operated systems, remote data
    acquisition, or multi-channel applications. The ADS7817 is
    available in a plastic mini-DIP-8, an SO-8, or an MSOP-8
    package. BIPOLAR INPUT RANGE

    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

    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

    Remove the DC Portion of Signals with the ADS7817
    Unwanted portions of a signal, such as a DC pedestal, can be difficult to reject in a single supply circuit. A DC pedestal voltage most typically appears at the output of an operational amplifier with a small signal riding on top of it. This pedestal voltage is required in the analog domain to insure that the small signal that contains the pertinent information never falls below the ground potenti

    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.
