EL2008

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 10

Ω 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 (1

Ω) gives a gain of 0.99 when driving a 100Ω

load and 0.9 driving a 10

Ω 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.
