Note 1: When operating at elevated temperatures the power dissipation of the EL2004 must be limited to the values shown in the
typical performance curve ‘‘Maximum Power Dissipation vs Temperature’’. Junction to case thermal resistance is 31 C/W
§
when dissipation is spread among the transistors in a normal AC steady-state condition. In special conditions where heat is
concentrated in one output device, junction temperature should be calculated using a thermal resistance of 70 C/W.
§
Note 2: Specification is at 25 C junction temperature due to requirements of high-speed automatic testing. Actual values at operating

may rise 40 C to 60 C above ambient and more under load conditions. Accordingly, V may change one to several mV, and

Note 4: Bandwidth is calculated from the rise time. The EL2004 has a single pole gain and phase response up to the 3 dB
frequency.
