CLC432  Product Folder

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 DC-coupled 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 without out voltage swings up to 28V_pp. A wide range of bandwidth insensitive 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 (0.2µs/1µs) 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°; A_V = +2V/V at 4.43MHz into 150 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
