[Sample requests now being accepted!] Ultra-high precision, sine wave VCO module with all-analog processing.

A "voltage-controlled" sine wave oscillator module characterized by a wide variable range, fast response speed (within 1 mS), and low distortion (below 0.1%). The practical variable range is ten thousand times, and the high-precision range is one thousand times. The setting frequency accuracy (linearity) is extremely high, within 1%. It maintains a flat amplitude characteristic within ±0.5 dB even in the ten thousand times range. It is a high-performance compact module that is easy to integrate, guarantees long-term stability with a pure electronic design, and offers a rich lineup including logarithmic frequency setting and 90-degree phase-shifted output.

basic information

**Features** ■ Miniaturization of high-performance circuit modules Contributes to space reduction, cost reduction, and assembly labor savings. ■ Long-term stable operation By using epoxy or silicone filling, it protects against temperature, humidity, dust, etc. (Products incorporated since the initial release in the mid-1980s are still operational.) ■ Easy integration Being analog-based, there is no need for design of peripheral software. (Generally, connecting a power supply of ±12V to 16V and control voltage will allow immediate operation. There is virtually no interference from random noise.) ■ Wide variable range Depending on the model, the range is broad, from 2,000 times to over 10,000 times, and remains stable over a long period. Aging changes are minimal. *We mainly handle products that cover the audio frequency range, but depending on the model, the oscillation frequency can range from DC to 250 kHz. The delivery time for standard products is approximately three weeks, and we can deliver immediately depending on stock availability. Many module products can be made thinner through packaging methods, so please consult us if you desire a slim and lightweight design.
