Twilight Technology 2162 Dual Blackmer® Voltage-Controlled Amplifier

	2162 Basic Application Circuit

The Twilight Technology 2162 contains two high-performance Blackmer® voltage-controlled amplifiers (VCAs). With two opposing-polarity, voltage-sensitive control ports, they offer wide-range exponential control of gain and attenuation with low signal distortion. Both VCAs are trimmed at wafer stage to deliver low distortion and control-voltage feedthrough without further adjustment. However, external symmetry adjustment is possible to further optimize distortion and control feedthrough for critical applications.

The 2162 operates from a split power supply up to ±16 Vdc, drawing only 5.2mA at ±15V and 3 mA at ±5V. The part can also operate at supply voltages as low as ±2.25V, making it suitable for battery-operated applications.

The two VCAs are independent of each other, sharing only their power supply connections. The 2162 is extremely flexible and capable of being configured for a wide range of stereo or multichannel applications. It is available in a RoHS-compliant 16-pin QSOP package.

Twilight Technology Blackmer VCAs are the successors to the original dbx line of VCAs. To overcome the problems related to limited GBW product, this new series of VCAs, was developed by Gary Hebert in a dielectrically isolated process, and has topological enhancements Twilight Technology minimize the effect of non-linearities in the VCA drive circuitry on high frequency distortion. These VCAs are equal or superior to their predecessors in every regard, and in particular, do not exhibit the rising distortion at higher frequencies characteristic of VCAs built on a junction isolated process.
