    Amplifier/Driver Family
    FEATURES DESCRIPTION n The LTCВ®1992 product family consists of five fully differential, low power amplifiers. The LTC1992 is an unconstrained
    fully differential amplifier. The LTC1992-1, LTC1992-2,
    LTC1992-5 and LTC1992-10 are fixed gain blocks (with
    gains of 1, 2, 5 and 10 respectively) featuring precision
    on-chip resistors for accurate and ultrastable gain. All of
    the LTC1992 parts have a separate internal common mode
    feedback path for outstanding output phase balancing
    and reduced second order harmonics. The VOCM pin sets
    the output common mode level independent of the input
    common mode level. This feature makes level shifting of
    signals easy. Available with Adjustable Gain or Fixed Gain of 1,
    2, 5 or 10
    ±0.3% (Max) Gain Error from –40°C to 85°C
    3.5ppm/В°C Gain Temperature Coefficient
    5ppm Gain Long Term Stability
    Fully Differential Input and Output
    CLOAD Stable up to 10,000pF
    Adjustable Output Common Mode Voltage
    Rail-to-Rail Output Swing ...

    Signal Designs – Design Note 333

    The block diagram in Figure 2 shows the general
    configuration of the differential-in/differential-out
    CMOS amplifier core, along with an output common
    mode servo. The values of the on-chip gain resistors
    depend on the dash suffix of the device as indicated. A
    convenient on-chip voltage-divider resistor network is
    also provided to support applications where a source
    of mid-supply potential (VMID) is needed.
    The LTC1992 is easy to use. Any signal difference at
    the inputs (within the input common mode range) are
    amplified and presented as a voltage difference at the output pins with a gain bandwidth product of about
    4MHz. The differential gain, A, is set by resistor values:
    A = RF/RG
    Any input common mode induced errors, primarily
    caused by small mismatches of resistor values, appear
    at the output as differential error. The common mode
    (shared offset) of the output pair is (VOUT+ + VOUT–)/2
    and independently governed to track the user-supplied
    VOCM output common mode control voltage (VOCM may
    be simply strapped to VMID if desired). The uncommitted LTC1992 (no dash suffix) may be user configured ...

    DESIGN FEATURES Fully Differential Gain-Block Family
    Simplifies Interface Designs by Jon Munson
    Introduction The LTC1992 product family provides
    simple amplification or level translation solutions for amplifying signals
    that are intrinsically differential or
    need to be made differential.
    The LTC1992 is available with uncommitted gain (base LTC1992), or in
    fixed gain versions with space-saving
    on-chip factory-trimmed resistors—
    namely, the LTC1992-1, LTC1992-2,
    LTC1992-5, and LTC1992-10, where
    the nominal gain is indicated by the
    suffix dash-number.
    Figure 1 shows a typical gain-of10 application where all gain setting
    components are included in the tiny
    MSOP-8 package. The device offers
    output common-mode control that
    operates completely independent
    from the input common-mode of the
    applied signal. The inputs and outputs can be used either differentially
    or single-ended as needed.
    The LTC1992 family operates with
    supply voltages from 2.7V single-supply to В±5V and typically consumes ...
