General Description
The Comlinear CLC2000 is a dual voltage feedback amplifier that offers
±200mA of output current at 9.4Vpp. The CLC2000 is capable of driving
signals to within 1V of the power rails. When connected as a differential line
driver, the dual amplifier drives signals up to 18.8Vpp into a 25Ω load, which
supports the peak upstream power levels for upstream full-rate ADSL CPE
applications.
The Comlinear CLC2000 can operate from single or dual supplies from 5V to
12V. It consumes only 7mA of supply current per channel. The combination
of wide bandwidth, low noise, low distortion, and high output current capabil-
ity makes the CLC2000 ideally suited for Customer Premise ADSL or video line
driving applications.
