XR-8038A  
May 1994-4  
Precision Waveform Generator  
GENERAL DESCRIPTION  
PIN ASSIGNMENT  
The XR-8038A is a precision waveform generator IC  
capable of producing sine, square, triangular, sawtooth,  
and pulse waveforms, with a minimum number of exter-  
nal components and adjustments. The 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 fre-  
quency, 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 volt-  
age 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 simul-  
taneously available from independent output terminals.

The XR-8038A monolithic waveform generator uses  
advanced processing technology and Schottky-barrier  
diodes to enhance its frequency performance. It can be  
readily interfaced with a monolithic phase-detector circuit,  
such as the XR-2228 to form stable phase-locked circuits.

SYSTEM DESCRIPTION  
FEATURES  
The XR-8038A precision waveform generator produces  
highly stable and sweepable square, triangle, and sine  
waves across eight frequency decades. The XR-8038A  
is an advanced version of the XR-8038, with improved  
sine distortion temperature drift. The device time base em-  
ploys resistors and a capacitor for frequency and duty cycle  
determination. The generator contains dual comparators,  
a flip-flop driving a switch, current sources, buffers, and  
a sine wave convertor. Three identical frequency outputs  
are simultaneously available. Supply voltage can range  
from 10V to 30V, or ±5V to ±15V with dual supplies.

APPLICATIONS

Sweep and FM Generation  
Tone Generation  
Instrumentation and Test Equipment Design  
Precision PLL Design  
Unadjusted sine wave distortion is typically less than  
0.7% with the sine wave distortion adjust pin (Pin 1) open.  
Distortion levels may be improved by including a 100kΩ  
potentiometer between the supplies, with the wiper con-  
nected to Pin 1.  
ABSOLUTE MAXIMUM RATINGS  
Small frequency deviation (FM) is accomplished by ap-  
plying modulation voltage to Pins 7 and 8; large frequency  
deviation (sweeping) is accomplished by applying volt-  
age to Pin 8 only. Sweep range is typically 1000:1.

The square wave output is an open collector transistor;  
output amplitude swing closely approaches the supply volt-  
age. Triangle output amplitude is typically 1/3 of the  
supply, and sine wave output reaches 0.22 of the supply  
voltage.
