NE5532N NE5532N
    A dual op-amp designed
    for use in high quality
    and professional audio
    equipment. The IC has a
    typical input noise
    voltage at 1kHz of
    5nVvHz. In addition it
    has better output drive
    capabilities and much
    higher small signal and
    power bandwidths than
    most other dual op-amps
    yet is a direct
    pin-for-pin replacement
    for a 1458.

LM13700N LM13700N
    The 13700 is a dual
    operational
    transconductance
    amplifier with
    linearising diodes and
    buffers. It consists of
    two current controlled
    transconductance
    amplifiers each with
    different inputs and a
    push pull output. The two
    amplifiers share common
    supplies but otherwise
    operate independently.
    Linearising diodes are
    provided at the inputs to
    reduce distortion and
    allow higher input
    levels. The result is a
    10dB signal-to-noise
    improvement referenced to
    0.5 THD. High impedance
    buffers are provided
    which are specially
    designed to complement
    the dynamic range of the
    amplifiers.The IC has

LM393N LM393N
LM393N LM393N
    An independent precision
    voltage comparator
    designed specifically to
    operate from a single
    power supply over a wide
    range of voltages.
    Operation from split
    rails is possible and the
    low power supply current
    drain is independent of
    the magnitude of the
    power supply voltage.
    Unique to the LM393 is
    that the input
    common-mode voltage range
    includes ground even
    though operated from a
    single power supply
    voltage. Designed to
    directly interface with
    TTL and CMOS and when
    operated from a - supply
    will directly interface
    with MOS logic. The
    device is similar to the
    392 but offers much lower
    input offset voltage and
    draws only half the
    supply current.

    Designed to directly
    interface with TTL and

    interface with MOS logic
    where the low power drain
    of the LM339 is a

    An LED driver that will
    sequentially light ten
    LEDs when a gradually
    increasing voltage is
    applied to pin 5 dot mode
    or in bar mode all LEDs
    indicating voltages below
    input are lit. In dot
    mode there is a slight
    overlap so that at no
    point are all LEDs
    extinguished. A
    brightness control will
    set LED current between
    2mA and 30mA. The drivers
    are stackable and
    displays with 100 or more
    LEDs are possible. Supply
    voltage 3V to 18V. The
    driver that sets the
    indication points can be
    referenced to a wide
    range of voltages. The

    Low-cost high performance
    JFET input op-amps that
    will directly replace and
    out-perform the 741 in
    most applications. The
    devices are low noise
    have distortion figures
    of less than 0.02 over
    the audio band high slew
    rate 13Vmicros high input
    impedance 1012Omega and
    wide bandwidth. For the
    347 internal amplifier
    isolation is 120dB.
    Additionally the
    accurately matched JFET
    inputs provide very low
    input bias and offset
    currents. It is most
    important that input
    voltages never go more
    negative than the
    negative supply voltage
    or the device will be
    destroyed. The ICs are
    ideal for audio circuits
    as well as fast DA
    convertors high speed
    integrators and
    sample-and-hold
    circuits.The 351 is
    supplied in an 8-pin DIL
    package and the 347 is
    supplied in a 14-pin DIL
    package and is a quad
    version. Note that since
    the inputs are JFETs not
    MOSFETs no special
    handling is required.
