CLC405
Low Cost, Low Power, 110MHz Op Amp with Disable
n Ultra fast enable/disable times
n High output current: 60mA
General Description
The CLC405 is a low cost, wideband (110MHz) op amp
featuring a TTL-compatible disable which quickly switches
off in 18ns and back on in 40ns. While disabled, the CLC405
Applications
n Desktop video systems
n Multiplexers
has a very high input/output impedance and its total power
consumption drops to a mere 8mW. When enabled, the
CLC405 consumes only 35mW and can source or sink an
output current of 60mA. These features make the CLC405 a
versatile, high speed solution for demanding applications
that are sensitive to both power and cost.
n Video distribution
n Flash A/D driver
n High speed switch/driver
n High source impedance applications
n Peak detector circuits
n Professional video processing
n High resolution monitors
Utilizing National’s proven architectures, this current
feedback amplifier surpasses the performance of alternative
solutions and sets new standards for low power at a low
price. This power conserving op amp achieves low distortion
with −72dBc and −70dBc for second and third harmonics
respectively. Many high source impedance applications will
benefit from the CLC405’s 6MΩ input impedance And finally,
designers will have a bipolar part with an exceptionally low
100nA non-inverting bias current.
Frequency Response (AV= +2V/V)
With 0.1dB flatness to 50MHz and low differential gain and
phase errors, the CLC405 is an ideal part for professional
video processing and distribution. However, the 110MHz
−3dB bandwidth (AV= +2) coupled with a 350V/µs slew rate
also make the CLC405 a perfect choice in cost sensitive
applications such as video monitors, fax machines, copiers,
and CATV systems.
