EL2008C

EL2008C EL2008C 55 MHz 1 Amp Buffer Amplifier Features High slew rate 2500 V/µs Wide bandwidth 100MHz @ RL = 50Ω and 55MHz @ RL = 10Ω Output current 1A continuous Output impedance 1Ω Quiescent current 13mA Short circuit protected Power package with isolated metal tab General Description 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 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 EL2008C. Used as an open loop buffer, the EL2008C's low output impedance (1Ω) gives a gain of 0.99 when driving a 100Ω load and 0.9 driving a 10 Ω 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. The EL2008C is constructed using Elantec's proprietary Complementary 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 temperature range and ...
