Voltage Controlled Oscillators ( VCO )

AS3340 / AS3345 - Voltage Controlled
Oscillators ( VCO ) |
TThe AS 3340 and AS 3345 are completely self contained, precision
voltage controlled oscillators, featuring both exponential and linear
control scales and up to four buffered output waveforms: triangle,
sawtooth, square, and pulse with voltage controllable pulse width. Full
temperature compensation makes these VCOs extremely stable, and
eliminates the need for a temperature compensation resistor. The highly
accurate exponential and linear control inputs are virtual ground
summing nodes, allowing mul¬tiple control voltages to be mixed within
the device itself.
