The AS3340A offers improvements over the original AS3340 including improved frequency stability against Vcc and VEE . Frequency stability can be improved If external reference voltage (with level approximately 1/3 Vcc) is connected to pin 9 (Soft Sync. Input). Also, improved symmetry of rising and falling edge of triangle signal (approx.. 50%).

The AS3340 is a completely self contained, precision voltage controlled oscillator, featuring both exponential and linear control scales. Up to four buffered output waveforms: triangle, sawtooth, square, and pulse. Vontrollable 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 multiple control voltages to be mixed within the device itself.
Also included is provision for hard and soft synchronization of the frequency, and an output for easy adjustment of high frequency tracking. Special care in the design ensures oscillation start-up under any power-on sequence and supply conditions.
