EL2008C
55 MHz 1 Amp Buffer Amplifier
Features
General Description
• High slew rate 2500 V/µs
• Wide bandwidth 100MHz @ RL =
50W and 55MHz @ RL = 10W
• Output current 1A continuous
• Output impedance 1W
• Quiescent current 13mA
• Short circuit protected
The EL2008C is a patented high speed bipolar monolithic buffer
amplifier designed to provide currents over 1 amp at high frequencies,
while drawing only 13 mA of quiescent supply current. The
EL2008C's 1500 V/µs slew rate and 55 MHz bandwidth driving a 10W
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 EL2008C.
Used as an open loop buffer, the EL2008C's low output impedance
(1W) gives a gain of 0.99 when driving a 100W load and 0.9 driving a
10W load. The EL2008C has output short circuit current limiting
which will protect the device under both a DC fault condition and AC
operation with reactive loads.
• Power package with isolated metal
tab
Applications
• Video distribution amplifier
• Fast op amp booster
• Flash converter driver
• Motor driver
• Pulse transformer driver
• A.T.E. pin driver
The EL2008C is constructed using Elantec's proprietary Complemen-
tary Bipolar process that produces PNP and NPN transistors with
essentially identical AC and DC characteristics. In the EL2008C, 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.
The EL2008CT is specified for operation over the 0°C to +75°C tem-
perature range and is provided in a 5-lead TO-220 plastic power
package.
