    LTC1290
    Single Chip 12-Bit Data
    Acquisition System U FEATURES DESCRIPTIO в–  The LTCВ®1290 is a data acquisition component which
    contains a serial I/O successive approximation A/D converter. It uses LTCMOSTM switched capacitor technology
    to perform either 12-bit unipolar or 11-bit plus sign bipolar
    A/D conversions. The 8-channel input multiplexer can be
    configured for either single-ended or differential inputs (or
    combinations thereof). An on-chip sample-and-hold is
    included for all single-ended input channels. When the
    LTC1290 is idle it can be powered down with a serial word
    in applications where low power consumption is desired. в–

    New 12-Bit Data Acquisition Systems Communicate with Microprocessors Over 4 Wires

    New 12-Bit Data Acquisition Systems Communicate with
    Microprocessors Over 4 Wires – Design Note 22
    As board space and semiconductor package pins become
    more valuable, serial data transfer methods between
    microprocessors (MPUs) and their peripherals become
    more and more attractive. Not only does this save lines
    in the transmission medium, but, because of the savings
    in the package pins, more function can be packed into
    both the MPU and the peripheral. Users are increasingly
    able to take advantage of these savings as more MPU
    manufacturers develop serial ports for their products (1-3).
    However, peripherals which are able to communicate with
    these MPUs must be available in order for users to take full
    advantage. Also, MPU serial formats are not standardized
    so not all peripherals can talk to all MPUs.
    The LTCВ®1290 Family
    A new family of 12-bit data acquisition circuits has been
    developed to communicate over just 4 wires to the recently
    developed MPU synchronous serial formats as well as
    to MPUs which do not have serial ports. These circuits
    feature software configurable analog circuitry including analog multiplexers, sample and holds, bipolar and
    unipolar conversion modes and the ability to shut power
    completely off. They also have serial ports which can be ...

    12-Bit 8-Channel Data Acquisition System Interfaces to IBM PC Serial Port

    12-Bit 8-Channel Data Acquisition System Interfaces to IBM PC
    Serial Port – Design Note 35
    Guy Hoover and William Rempfer
    IBM PCs Collect Analog Data
    IBM PC compatibles can be found just about everywhere.
    In those instances where a PC is not already in place,
    battery operated portables are readily available. This
    makes the PC a good choice for controlling a data acquisition system. Typically, such data acquisition systems
    have been expensive. Using dedicated A/D cards or
    IEEE-488 controllers and instruments, these systems
    tie up slots in the PC and are not readily transportable
    from one machine to another. As an alternative, the
    schematic of Figure 1 shows a 12-bit, 8-channel data
    acquisition system that connects to the serial port of
    the PC. This system uses an LTC В®1290, a reference,
    a handful of other low cost components and requires
    12 lines of BASIC to transfer data into the PC. If only
    ten bits of resolution are required the LTC1290 can be
    replaced with an LTC1090. Additionally, if the LTC1090
    is used, the system can be powered directly from the
    PC serial port with the option shown. Two Glue Chips Provide the Interface
    The control and status lines of the PC serial port are
    used to send data to and receive data from the LTC1290. ...

    Signal Conditioning for Platinum Temperature Transducers

    Signal Conditioning for Platinum Temperature Transducers
    Design Note 45
    Jim Williams
    High accuracy, stability, and wide operating range make
    platinum RTDs (resistance temperature detectors)
    popular temperature transducers. Signal conditioning
    these devices requires care to utilize their desirable
    characteristics. Figure 1’s bridge-based circuit is highly
    accurate and features a ground referred RTD. The ground
    connection is often desirable for noise rejection. The
    bridges RTD leg is driven by a current source while the
    opposing bridge branch is voltage biased. The current
    drive allows the voltage across the RTD to vary directly
    with its temperature induced resistance shift. The difference between this potential and that of the opposing
    bridge leg forms the bridges output.
    A1A and instrumentation amplifier A2 form a voltage
    controlled current source. A1A, biased by the LTВ®1009
    reference, drives current through the 88.7О© resistor and
    the RTD. A2, sensing differentially across the 88.7Ω resistor, closes a loop back to A1A. The 2k-0.1μF combination sets amplifier roll-off, and the configuration
    is stable. Because A1A’s loop forces a fixed voltage
    across the 88.7О© resistor, the current through Rp is
    constant. A1’s operating point is primarily fixed by the
    2.5V LT1009 voltage reference. ...

    Gain Trimming In Instrumentation Amplifier Based Systems

    Gain Trimming In Instrumentation Amplifier
    Based Systems – Design Note 51
    Jim Williams
    Gain trimming is almost always required in instrumentation amplifier based systems. Gain uncertainties, most
    notable in transducers, necessitate such a trim.
    Figure 1, a conceptual system, shows several points as
    candidates for the trim. In practice, only one of these
    must actually be used. The appropriate trim location
    varies with the individual application.
    Figure 2 approaches gain trimming by altering transducer excitation. The gain trim adjustment results in
    changes in the LT®1010’s output. The LT1027 reference
    and LT1097 ensure output stability. Transducer output varies with excitation, making this a viable approach.
    It is important to consider that gain “lost” by reducing
    transducer drive translates into reduced signal-to-noise
    ratio. As such, gain reduction by this method is usually
    limited to small trims, e.g., 5-10%. Similarly, too much
    gain introduced by this method can cause excessive
    transducer drive, degrading accuracy. The transducer
    manufacturer’s data sheet should list the maximum
    permissible drive for rated accuracy.
