    в—Џ EXTERNAL REFERENCE The ADS1250 is a precision, wide dynamic range,
    delta-sigma, analog-to-digital converter with 20-bit
    resolution operating from a single +5V supply. The
    delta-sigma architecture is used for wide dynamic
    range and to guarantee 20 bits of no missing code
    performance. An effective resolution of 18 bits (2.8ppm
    of rms noise) is achieved for conversion rates up to
    25kHz. The dynamic range of the converter is further
    increased by providing a low-noise Programmable
    Gain Amplifier (PGA) with gain stages of 1, 2, 4, or
    8 for low level input signals.
    The ADS1250 is designed for high-resolution measurement applications in cardiac diagnostics, smart ...

    A Spreadsheet for Calculating the Frequency Response of the ADS1250-54 (Rev. A)
    The ADS1250, ADS1251, ADS1252, ADS1253 and ADS1254 family of high-resolution analog-to-digital converters (ADCs) share an advanced delta-sigma (О”ОЈ) topology. This application note reviews the frequency characteristics of these devices and shows how to use a companion Microsoft Excel? spreadsheet (sbaa103a.zip), available for download from the TI web site, to calculate the frequency res

    AB-174: Getting the Full Potential from your ADC (Rev. A)
    Many of today?s high-resolution ADCs (Analog-to-Digital Converters) are operating from a single supply and use fully differential inputs. This can be a problem for single-ended signals that are bipolar relative to common. This article illustrates circuit configurations that preserve the full-scale input range by using modern features, such as Programmable Gain Amplifiers (PGAs) and internal voltag
