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.
