The document discusses the ICL8038 function generator integrated circuit. It can produce sine, square, triangular, sawtooth, and pulse waveforms using minimal external components. The frequency can be selected from 0.001Hz to over 300kHz using resistors or capacitors. It has features like low frequency drift with temperature, low distortion, high linearity, and wide frequency range. It can simultaneously output sine, square, and triangle waves.
2. INTRODUCTION.
The ICL8038 waveform generator is a
monolithic integrated circuit capable of
producing high accuracy sine, square,triangular,
sawtooth and pulse waveforms with a minimum
of external components.
The frequency (or repetition rate) can be
selected externally from 0.001Hz to more than
300kHz using either resistors or capacitors, and
frequency modulation and sweeping can be
accomplished with an external voltage.
3. FEATURES.
Low Frequency Drift with Temperature .
Low Distortion
High Linearity
Wide Frequency Range
Simultaneous Sine, Square, and Triangle
Wave Outputs
7. WORKING.
The ICL8038 is a function generator chip
that can generate three basic signals such as
Sine, Square and triangle waveforms. The IC
has also provided room to adjust the
important parameters of a waveform such as
Frequency and duty cycle.
9. APPLICATIONS.
The sine wave output has a relatively high
output impedance (1kΩ Typ).
Its high frequency stability makes the
ICL8038 an ideal building block for a phase
locked loop_x0000_ _x0000_
10. ADVANTAGES.
Less number of external components.
Low cost
Easy to bound circuit
Generates precise waveform
