General Description
The Comlinear CLC2000 and CLC4000 are dual and quad voltage feedback amplifiers that offer ±200mA of output current at 9.4Vpp. The CLC2000 and CLC4000 are capable of driving signals to within 1V of the power rails. When connected as a differential line driver, the 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.
