THAT 2181 / 2180 Series Voltage Controlled Amplifiers

These devices are critical elements in a wide range of audio products such as

compressors, limiters, automatic gain controls, noise reduction systems and automated

mixing consoles. They are available in a wide selection of performance grades with factory

trimmed or user trimmed options. They offer low noise and distortion, wide dynamic range

and a logarithmic control characteristic.

They are superior in performance to the THAT2150A; THAT2151 and THAT2155 legacy

VCAs. The link to these still available products can be found at the bottom of this page.

NEW - THAT 2162 Dual Blackmer^® Voltage-Controlled Amplifier

THAT 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.
