The CLC428 is a very high-speed dual op amp that offers a traditional voltage-feedback topology featuring unity-gain stability and slewenhanced circuitry. The CLC428's ultra low noise and very low harmonic distortion combine to form a very wide dynamic-range op amp that operates from a single (5 to 12V) or dual (±5V) power supply.

Each of the CLC428's closely matched channels provides a 160MHz unity-gain bandwidth with an ultra low input voltage noise density (2nV/Hz). Very low 2nd/3rd harmonic distortion (-62/-72dBc) as well as high channel-to-channel isolation (-62dB) make the CLC428 a perfect wide dynamic-range amplifier for matched I/Q channels.

With its fast and accurate settling (16ns to 0.1%), the CLC428 is also a excellent choice for wide-dynamic range, anti-aliasing filters to buffer the inputs of hi-resolution analog-to-digital converters. Combining the CLC428's two tightly-matched amplifiers in a single eight-pin SOIC reduces cost and board space for many composite amplifier applications such as active filters, differential line drivers/ receivers, fast peak detectors and instrumentation amplifiers.

To reduce design times and assist in board layout, the CLC428 is supported by an evaluation board and a SPICE simulation model available from National Semiconductor.
