    DFN Packages The LTCВ®6102/LTC6102HV are versatile, high voltage, highside current sense amplifiers. Their high supply voltage
    rating allows their use in many high side applications,
    while the low drift and offset ensure accuracy across a
    wide range of operating conditions. The LTC6102-1 is a
    version of the LTC6102 that includes a low power disable
    mode to conserve system standby power. n The LTC6102/LTC6102HV monitor current via the voltage
    across an external sense resistor (shunt resistor). Internal
    circuitry converts input voltage to output current, allowing ...

    INTRODUCTION
    Sensing and/or controlling current flow is a fundamental requirement in many electronics systems, and the
    techniques to do so are as diverse as the applications
    themselves. This Application Note compiles solutions to
    current sensing problems and organizes the solutions by
    general application type. These circuits have been culled
    from a variety of Linear Technology documents.
    Circuits Organized by General Application
    Each chapter collects together applications that tend to
    solve a similar general problem, such as high side current sensing, or negative supply sensing. The chapters are titled
    accordingly. In this way, the reader has access to many
    possible solutions to a particular problem in one place.
    It is unlikely that any particular circuit shown will exactly
    meet the requirements for a specific design, but the suggestion of many circuit techniques and devices should
    prove useful. To avoid duplication, circuits relevant to
    multiple chapters may appear in one location.

    Ultraprecise Current Sense Amplifier Dramatically Enhances
    Efficiency and Dynamic Range – Design Note 423
    Jon Munson
    Introduction
    Accurate current measurement is indispensable in many
    electronic systems. The current is usually measured by
    amplifying the voltage it generates across a small value
    resistance. For systems that require a large dynamic measurement range, the sense resistance must be increased or
    the precision of the amplifier must be improved. Increasing
    the value of the sense resistor has the detrimental effect
    of increasing power dissipation. The better option is to
    improve the precision of the sense amplifier.
    Amplifier precision depends a great deal on the input
    offset voltage of the amplifier. Historically, current sense
    amplifiers on the market offered input offset voltage
    performance on the order of hundreds or even thousands
    of ОјV. With such parts, achieving a practical dynamic
    range of 8 to 10 bits can cost more than a Watt of power
    dissipation at full operating current. The LTC ®6102 ultraprecise current sense amplifier reduces input error to a
    miniscule 10ОјV. This dramatic performance enhancement
    translates directly into a greater measurement dynamic
    range—16 bits is possible even while lowering power
    dissipation in the sense resistor—thus greatly expanding ...

    DESIGN FEATURES L Measure Microamps to Amps or
    Reduce Power Dissipation by 99%,
    by Brendan J. Whelan
    You Decide!
    Introduction Why Use High Side Sense?
    In many applications, the sense load
    is ground referred. The simplest way
    to measure current in these systems is
    low side sensing, which involves adding a small sense resistor between the
    load and the system ground (FigureВ 1).
    Almost any amplifier can be used to
    amplify the sense voltage, and no level
    translation is required.
    Low side sensing, for all its simplicity, has several inherent problems.
    First, the sense resistor affects the
    return voltage on the load—where
    the return is now the sum of the
    system’s ground potential and the
    voltage across the sense resistor. The
    load now floats above system ground
    by the sense voltage, which can be
    significant—a traditional low side
    current sense circuit of some precision requires a voltage around and ...

    DESIGN IDEAS L 3mm × 3mm, 16-Bit ADC Brings
    Accurate, Precise High Side
    Current Sensing to Tight Spaces
    by Leo Chen Introduction
    Power monitoring circuits are increasingly used throughout automotive,
    industrial, communications and
    computing applications as electronics
    designers strive to continually improve thermal performance, increase
    efficiency and generally make their
    products more “green.”
    The problem is that power monitoring always looks like the perfect feature
    until space and cost constraints come
    into play. Power monitoring is usually
    considered an ancillary function, so
    its footprint should be as small as
    possible to maximize space available
    to the main application. The LTC2460
    16-bit Delta-Sigma ADC solves the
    space and design cost problem when
    paired with one of Linear Technology’s
    current sense amplifiers, such as the
    LTC6102.
    The LTC2460 proves that big-feature ADCs can come in tiny packages. ...
