【Sample requests now being accepted!】 Ultra-high precision, low-frequency VCF module with all-analog processing.
All types of filters with characteristics such as LP, BP, HP, and BEF (bandwidth removal) are fully equipped. The variable range of the "cutoff (center) frequency" is extensive, over a thousand times. With a control voltage from +10 mV to +10 V, there is practically infinite setting resolution. The set frequency is accurately proportional to the control voltage (with an error of about 1% or less). The pass characteristics also have an error of within 0.5 dB across the entire range. It is not a photocoupler but a pure electronic type, ensuring fast response and stable operation over long periods. It features an easy-to-use pin layout. Due to analog processing, it has low noise and a wide dynamic range of over 80 dB.

basic information
**Features** ■ Miniaturization of high-performance circuit modules Contributes to space reduction, cost reduction, and assembly labor reduction. ■ 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, it operates immediately with a standard power supply of ±12V to 16V and an appropriate control voltage. No noise generation.) ■ Variable range of over 1,000 times (using pure electronic variable resistor elements) Filters: variable range of over 1,000 times Oscillators: over 10,000 times, wide and stable over long periods. *We mainly handle products that cover the audio frequency range, but depending on the model, the operating range can be DC to 1 MHz. Standard delivery time is approximately three weeks, with immediate delivery 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.
