CLC431

The CLC431 and CLC432 current-feedback amplifiers provide wide bandwidths and high slew rates for applications where board density and power are key considerations. These amplifiers provide DCcoupled small signal bandwidths exceeding 92MHz while consuming only 7mA per channel. Operating from ±15V supplies, the CLC431/ 432's enhanced slew rate circuitry delivers large-signal bandwidths with output voltage swings up to 28Vpp. A wide range of bandwidthinsensitive gains are made possible by virtue of the CLC431 and CLC432's current-feedback topology.

The large common-mode input range and fast settling time (70ns to 0.05%) make these amplifiers well suited for CCD & data telecommunication applications. The disable of the CLC431 can accommodate ECL or TTL logic levels or a wide range of user definable inputs. With its fast enable/disable time (0.2ms/1ms) and high channel isolation of 70dB at 10MHz, the CLC431 can easily be configured as a 2:1 MUX. Many high performance video applications requiring signal gain and/or switching will be satisfied with the CLC431/432 due to their very low differential gain and phase errors (less than 0.1% and 0.1°; Av = +2V/V at 4.43MHz into 150W load).

Quick 8ns rise and fall times on 10V pulses allow the CLC431/432 to drive either twisted pair or coaxial transmission lines over long distances.

The CLC431/432's combination of low input voltage noise, wide common-mode input voltage range and large output voltage swings make them especially well suited for wide dynamic range signal processing applications.
