ZETEX ZXFBF04N14TA

ZXFBF04
4 Channel Buffer Device
APPLICATIONS
DEVICE DESCRIPTION
The ZXFBF04 is a low cost, high slew rate, quad buffer
amplifier. Built using the Zetex CA700 technology, this
buffer has a small signal bandwidth of greater than
100MHz and a 1 volt pk-pk bandwidth of greater than
20 MHz. Each channel draws only 1.9mA. The device
operates from a ±5 volt supply, which makes it ideal in
a majority of applications.
This space saving buffer may be used in a wide variety
of applications such as, video switching matrix,
multi-channel instrumentation equipment, and A/D
input buffer, etc.
