2162 Dual Voltage
Controlled Amplifier |
New York, NY - THAT
Corporation will unveil the new THAT 2162, the company's first dual
Blackmer® voltage controlled amplifier (VCA) IC at the 123rd Audio
Engineering Society (AES) Convention. The part is a low-cost,
space-saving solution for multi-channel VCA applications.
Les Tyler, THAT's president, noted "The 2162
is basically a pair of our famous Blackmer VCAs integrated into one
package. The part delivers great performance in a tiny package,
offering 118dB dynamic range, 130dB gain-control range, and distortion
under 0.1% without any adjustment. Performance-conscious designers can
reduce THD further by using an external trim, if desired."
Packaged in a 16-pin QSOP package, the 2162's two VCAs are
independent of each other, sharing only their power supply
connections. Both positive- and negative-sense control ports are
brought out separately for each VCA. As a result, the part can be
configured for a wide range of stereo and multichannel applications.
Gary Hebert, THAT's chief technology officer and designer of the IC
pointed out that "the 2162 operates over a wide range of (split)
power supply voltages, from ±16 Vdc to as low as ±2.25V. It draws
only 3mA at ±5V supplies, so it is suitable even for for
battery-operated applications. Moreover, our Blackmer architecture
uses current, not voltage, for input and output signals. So, the
2162's wide dynamic range is hardly compromised by low-voltage
operation."
Fabricated in THAT's proprietary dielectric isolation (DI) process
at its Milpitas, CA IC foundry, the 2162 delivers discrete analog
circuit performance with the reliability and cost benefits of an
integrated circuit. Mr. Hebert explained, "Conventional
junction-isolated (JI) ICs suffer from parasitic diodes (and their
associated capacitance) between critical components and a common
substrate which can compromise performance. Discrete implementations
(on a PCB) suffer from temperature drift, and difficulty in matching
the discrete components. Our DI process significantly reduces many of
the parasitics suffered by JI ICs, and maintains excellent thermal
tracking and device matching over the entire circuit. We get the best
of both discrete and monolithic design, which we put to good use in
the 2162."
The THAT
2162 is available immediately in a RoHS-compliant 16-pin QSOP
package. Samples, 2162
datasheets and
additional information on the 2162 and other THAT Corporation ICs are
available at THAT's booth at the 123rd AES Convention or by contacting
