EL2009C

The EL2009 is a patented high speed bipolar monolithic buffer amplifier designed to provide currents over 1 amp at high frequencies, while drawing 40 mA of quiescent supply current. The EL2009's 3000 V/ms slew rate and 90 MHz bandwidth driving a 10X load insures stability in fast op amp feedback loops. Elantec has applied for patents on unique circuitry within the EL2009.

Used as an open loop buffer, the EL2009's low output impedance (1X) gives a gain of 0.99 when driving a 100X load and 0.9 driving a 10X load.

The EL2009 has an output short circuit current limit which will protect the device under both a DC fault condition and AC operation with reactive loads.

The EL2009 is constructed using Elantec's proprietary Complementary Bipolar process that produces PNP and NPN transistors with essentially identical AC and DC characteristics. In the EL2009, 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 EL2009CT is specified for operation over the 0§C to a75 temperature range and is provided in a 5-lead TO-220 plastic power package.
