Dual voltage controlled amplifier targets multi-channel apps

Milford, Mass. — THAT Corp. has introduced the THAT 2162, the company's first dual voltage controlled amplifier (VCA) IC as part of its Blackmer family. Designed for multi-channel VCA applications, the 2162 integrates a pair of the company's Blackmer VCAs in a 16-pin QSOP package.

Fabricated in THAT's proprietary dielectric isolation (DI) process, the 2162 device offers a 118 dB dynamic range, 130 dB gain-control range, and distortion under 0.1% without any adjustment. THD can be reduced by using an external trim, said THAT Corp. The dual VCA operates over a wide range of (split) power supply voltages from ±16 Vdc to as low as ±2.25 V. Since it draws only 3 mA at ±5-V supplies, it is suitable for battery-operated applications.

The 2162 device's two integrated VCAs are independent of each other, sharing only their power supply connections. Both positive- and negative-sense control ports are separate for each VCA. As a result, the part can be configured for a wide range of stereo and multi-channel applications, said the company.

Availability: Available now in a RoHS-compliant 16-pin QSOP package.

Product information: 2162 Series
