GENERAL DESCRIPTION
The XR-2206 is a monolithic function generator
integrated circuit capable of producing high quality sine,
square, triangle, ramp, and pulse waveforms of
high-stability and accuracy. The output waveforms can be
both amplitude and frequency modulated by an external
voltage. Frequency of operation can be selected
externally over a range of 0.01Hz to more than 1MHz.
The circuit is ideally suited for communications,
instrumentation, and function generator applications
requiring sinusoidal tone, AM, FM, or FSK generation. It
has a typical drift specification of 20ppm/°C. The oscillator
frequency can be linearly swept over a 2000:1 frequency
range with an external control voltage, while maintaining
low distortion.
