The ENI 1140LA is an all solid state power amplifier operating over the range of 9 kHz to 250 kHz with a flat gain of 55 dB. Its 50 ohm input is compatible with most laboratory signal generator, function generator, or integrated circuit oscillator. Any load impedance may be connected to the output of the 1140LA without fear of damge or oscillation. The ENI 1140LA delivers maximum power transfer to a 50 ohm load impedance, however, any load impedance between 2 and 800 ohms can be driven by connecting a matching transformer between the output and the load.
