GENERAL DESCRIPTION
The XR-8038A is a precision waveform generator IC
capable of producing sine, square, triangular, sawtooth,
and pulse waveforms, with a minimum number of external
components and adjustments. The XR-8038A allows the
elimination of the external distortion adjusting resistor
which greatly improves the temperature drift of distortion,
as well as lowering external parts count. Its operating
frequency can be selected over eight decades of
frequency, from 0.001Hz to 200kHz, by the choice of
external R-C components. The frequency of oscillation is
highly stable over a wide range of temperature and supply
voltage changes. Both full frequency sweeping as well as
smaller frequency variations (FM) can be accomplished
with an external control voltage. Each of the three basic
waveform outputs, (i.e., sine, triangle and square) are
simultaneously available from independent output
terminals.
The XR-8038A monolithic waveform generator uses
advanced processing technology and Schottky-barrier
diodes to enhance its frequency performance.
