CLC426
Wideband, Low-Noise, Voltage Feedback Op Amp
General DescriptionThe CLC426 combines an enhanced voltage-feedback architecture
with an advanced complementary bipolar process to provide a
high-speed op amp with very low noise (1.6nV/√Hz & 2.0pA/√Hz) and
distortion (-62/-68dBc 2nd/3rd harmonics at 1Vpp and 10MHz).
Providing a wide 230MHz gain-bandwidth product, a fast 400V/μs
slew rate and very quick 16ns settling time to 0.05% , the CLC426 is
the ideal choice for high speed applications requiring a very wide-
dynamic range such as an input buffer for high-resolution analog-to-
digital converters.
The CLC426 is internally compensated for gains ≥ 2V/V and can
easily be externally compensated for unity-gain stability in applications
such as wideband low-noise integrators. The CLC426 is also equipped
with external supply current adjustment which allows the user to
optimize power, bandwidth, noise and distortion performance for each
application.
The CLC426's combination of speed, low noise and distortion and low
dc errors will allow high-speed signal conditioning applications to
achieve the highest signal-to-noise performance. To reduce design
times and assist board layout, the CLC426 is supported by an
evaluation board and SPICE simulation model available from National.
For even higher gain-bandwidth voltage-feedback op amps see the
1.9GHz CLC425 (Av ≥ 10V/V) or the 5.0GHz CLC422 (Av ≥ 30V/V).
