    1290 Series Basic Application Circuit

    DESCRIPTION

    The THAT 1290 series of low-cost dual precision differential amplifiers was designed primarily for use as balanced line receivers for audio applications.

    These devices include on-board precision thin-film resistors which offer good matching and excellent tracking due to their monolithic construction.

    The 1290 series is available in a 16-pin QSOP package which features a very small footprint.
