• Description: Triple 600mhz Current Feedback Amplifier With Enable
• Manufacturer: Intersil Corporation

Applications Information
Product Description
The EL5392A is a current-feedback operational amplifier
that offers a wide -3dB bandwidth of 600MHz and a low
supply current of 6mA per amplifier. The EL5392A works
with supply voltages ranging from a single 5V to 10V and
they are also capable of swinging to within 1V of either
supply on the output. Because of their current-feedback
topology, the EL5392A does not have the normal gain-
bandwidth product associated with voltage-feedback
operational amplifiers. Instead, its -3dB bandwidth to remain

relatively constant as closed-loop gain is increased. This
combination of high bandwidth and low power, together with
aggressive pricing make the EL5392A the ideal choice for
many low-power/high-bandwidth applications such as
portable, handheld, or battery-powered equipment.
For varying bandwidth needs, consider the EL5191 with
1GHz on a 9mA supply current or the EL5193 with 300MHz
on a 4mA supply current. Versions include single, dual, and
triple amp packages with 5 Ld SOT-23, 16 Ld QSOP, and
8 Ld or 16 Ld SOIC (0.150") outlines.
