55MHz 1 Amp Buffer Amplifier
The EL2008 is a patented high speed
bipolar monolithic buffer amplifier
designed to provide currents over 1
amp at high frequencies, while drawing only 13mA of
quiescent supply current. The EL2008’s 1500V/µs slew rate
and 55MHz bandwidth driving a 10Ω load is second only to
the EL2009 and insures stability in fast op amp feedback
loops. Elantec has applied for patents on unique circuitry
within the EL2008.
Used as an open loop buffer, the EL2008’s low output
impedance (1Ω) gives a gain of 0.99 when driving a 100Ω
load and 0.9 driving a 10Ω load. The EL2008 has output
short circuit current limiting which will protect the device
under both a DC fault condition and AC operation with
reactive loads.
The EL2008 is constructed using Elantec's proprietary
Complementary Bipolar process that produces PNP and
NPN transistors with essentially identical AC and DC
characteristics. In the EL2008, the Complementary Bipolar
process also insulates the package's metal heat sink tab
from all supply voltages. Therefore the tab may be mounted
to an external heat sink or the chassis without an insulator.
