CLC405
Low Cost, Low Power, 110MHz Op Amp with Disable
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
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.
Utilizing National's proven architectures, this current feed-
back amplifier surpasses the performance of alternative so-
lutions 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 respec-
tively. Many high source impedance applications will benefit
from the CLC405's 6M
input impedance. And finally, de-
signers will have a bipolar part with an exceptionally low
100nA non-inverting bias current.
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 (A
V
= +2) coupled with a 350V/s slew rate
also make the CLC405 a perfect choice in cost sensitive
applications such as video monitors, fax machines, copiers,
and CATV systems.
