Application Notes

    Delta Sigma ADC Bridge Measurement Techniques
    AN96 features several applications that demonstrate how to take full advantage of Linear Technology's delta sigma ADCs when interfacing to sensors. In many cases, signal conditioning can be greatly simplified or eliminated completely. This note explains where it is appropriate to use amplifiers and how to optimize amplifier gain. Also included are discussions on measuring effective number of bits (ENOB) and the relationship to instrument performance, frequency response of delta sigma ADCs, and test techniques. C source code for all of the applications is included to aid firmware development.

    Application Note 96
    January 2005
    Delta Sigma ADC Bridge Measurement Techniques
    Mark Thoren
    Introduction In a typical 12-bit measurement system, the signal conditioning amplifier requires a very high gain in order to make
    use of the full ADC input range. A sensor with a 10mV fullscale output requires a gain of 500 to use the full input
    range of a typical 5V input ADC. A filter may be required to
    reduce noise at the expense of settling time. Additional
    difficulties arise when dealing with the large common
    mode voltage typical of a bridge sensor. Most instrumentation amplifiers have a large discrepancy between the
    typical CMRR and guaranteed minimum, which may require an additional trim. Sensors for pressure, load, temperature, acceleration and
    many other physical quantities often take the form of a
    Wheatstone bridge. These sensors can be extremely linear
    and stable over time and temperature. However, most
    things in nature are only linear if you don’t bend them too
    much. In the case of a load cell, Hooke’s law states that the
    strain in a material is proportional to the applied stress—
    as long as the stress is nowhere near the material’s yield
    point (the “point of no return” where the material is
    permanently deformed). The consequence is that a load
    cell based on a resistance strain gauge will have a very
    small electrical output—often only a few millivolts. In
    spite of this, instruments with 100,000 counts of resolution and more are possible. This Application Note presents ...

    Low Power, DC Accurate Drivers for 18-Bit ADCs

    Low Power, DC Accurate Drivers for 18-Bit ADCs
    Guy Hoover A common misconception about 18-bit SAR ADCs is the only way to drive them
    is with a high powered, high speed, low noise op amp or differential driver whose
    DC performance often leaves much to be desired. It is possible to use a low
    power, DC accurate op amp to drive an 18-bit SAR ADC if the input is a DC or low
    bandwidth AC signal and the op amp outputs are given sufficient time to settle.
    Using the single-ended to differential driver of Figure 1, four different low power
    dual op amps were tested to show the trade-offs in using low power drivers.
    This circuit enables the testing of offset voltage, the maximum sample
    rate for DC and AC signals, noise and
    power consumption. The ADC used
    is the LTC2379-18, a 1.6Msps 18-bit
    SAR ADC with an offset of В±9LSBs, INL of
    В±2LSBs and peak-to-peak noise of 5LSBs.
    The four amplifiers used are the
    LT1013, LTC6078, LTC6081 precision and
    LTC2051HV zero-drift dual op amps—
    Table 1 shows a summary of their major
    specs. The circuit supply voltage is the
    voltage applied to the V+ and V– terminals
    of the op amps. This voltage determines
    the power dissipation of the amplifier and
    its maximum signal swing. The voltages ...

    Zero-Drift Operational Amplifier Family in Small-Footprint Packages Features 3µV Maximum DC Offset and30nV/°C Maximum Drift

    DESIGN FEATURES Zero-Drift Operational Amplifier Family
    in Small-Footprint Packages Features
    3ВµV Maximum DC Offset and
    30nV/В°C Maximum Drift
    by David Hutchinson
    Introduction Extended Input
    Common Mode Range
    with Uncompromising CMRR
    At room temperature, and with the
    input common mode level at midsupplies, the parts typically have
    0.5ВµV of input-referred offset and are
    guaranteed to have less than В±3ВµV.
    To ensure this DC accuracy over the
    common mode input range, the
    LTC2050/LTC2051/LTC2052 have 6 exceptionally high CMRR over a wide
    range from the negative supply to
    typically within 0.9V of the positive
    rail, as shown in Figure 1. For
    example, as the input is varied over
    the entire 5V common mode range,
    the input-referred offset changes typically by less than 0.4ВµV. Similar levels
    of PSRR (typically less than 0.1ВµV of
    offset per volt of supply change) and ...
