CLC428
Dual Wideband, Low-Noise, Voltage Feedback Op Amp
General Description
The CLC428 is a very high-speed dual op amp that offers a traditional
voltage-feedback topology featuring unity-gain stability and slew-
enhanced 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.
