for gains between 10 and 10. Built using the Elantec mono-
lithic Complementary Bipolar process, this amplifier uses cur-
rent mode feedback to achieve more bandwidth at a given gain

high slew rate of 2000 V/ms, the EL2030 drives 10V into 200X
at a frequency of 30 MHz, while achieving 110 MHz of small

The EL2030 features extremely low differential gain and phase,
a low noise topology that reduces noise by a factor of 2 over
competing amplifiers, and settling time of 40 ns to 0.25% for a
10V step. The output is short circuit protected. In addition, da-
