V2162

Dual Voltage Controlled Amplifier 1、Overview The V2162 is a dual voltage-controlled amplifier (VCA) that designed for typical applications such as audio compressors/limiters, equalizers and oscillators. The chip is a high-performance current-in/current-out device with two opposing-polarity, voltage-sensitive control ports in each channel. Fabricated in a low-noise process utilizing high h FE , complementary NPN/PNP pairs, the V2162 can offer high performance with minimal support circuitry. Its features are: ● Two Independent VCA Channels ● Wide Dynamic Range: >115dB ● Wide Gain Range: >130dB ● Exponential (dB) Gain Control ● Low Distortion: 0.04% typ. ● Dual Control Ports (pos/neg) ● Package: SOP16L
