ALFA RPAR AS3340-DIL Voltage Controlled Oscillator (VCO) (DIL-16)
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. An on-chip 7.4 volt Zener diode allows the device to operate off ±15 volt supplies, as well as +15,-5 volt supplies. To minimize self-heating and improve thermo-stability it is recommended to keep VEE = -5V (external power supply).
The AS3340 is also available in an SMT package.
