The AS3340A is 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.
AS3340A is an improved versions of AS3340. AS3340A has much more output 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). AS3340A benefits from improved symmetry of rising and falling edge of triangle signal (approx.. 50%).
Available in DIP-16 package.
