ZXFBF05
4 Channel Buffer Device with high capacitance load capability
DEVICE DESCRIPTION
The ZXFBF05 is a low cost, high slew rate, quad buffer
amplifier. Built usingthe 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 7.5mA. The device
operates froma ±5 volt supply, which makes itideal in
a majority of applications.
This space savingbuffer may beused in awide variety
of applications such as, video switching matrix,
multi-channel instrumentation equipment, and A/D
input buffer, etc.
