The MAX038 is a high-frequency, precision function  
generator producing accurate, high-frequency triangle,  
sawtooth, sine, square, and pulse waveforms with a  
minimum of external components. The output frequency  
can be controlled over a frequency range of 0.1Hz to  
20MHz b y a n inte rna l 2.5V b a nd g a p volta g e  
reference and an external resistor and capacitor. The  
duty cycle can be varied over a wide range by applying  
a ±2.3V control signal, facilitating pulse-width modula-  
tion a nd the g e ne ra tion of s a wtooth wa ve forms .  
Frequency modulation and frequency sweeping are  
a c hie ve d in the s a me wa y. The d uty c yc le a nd  
frequency controls are independent.
