FN7151
2GHz GBWP Gain-of-10 Stable
Operational Amplifier
The EL2075 is a precision voltage-
feedback amplifier featuring a 2GHz
gain-bandwidth product, fast settling
time, excellent differential gain and differential phase
performance, and a minimum of 50mA output current drive
over temperature.
The EL2075 is gain-of-10 stable with a -3dB bandwidth of
400MHz at A
V
= +10. It has a very low 200µV of input offset
voltage, only 2µA of input bias current, and a fully
symmetrical differential input. Like all voltage-feedback
operational amplifiers, the EL2075 allows the use of reactive
or non-linear components in the feedback loop. This
combination of speed and versatility makes the EL2075 the
ideal choice for all op-amp applications at a gain of 10 or
greater requiring high speed and precision, including active
filters, integrators, sample-and-holds, and log amps. The low
distortion, high output current, and fast settling makes the
EL2075 an ideal amplifier for signal-processing and
digitizing systems.
Features
• 2GHz gain-bandwidth product
• Gain-of-10 stable
• Conventional voltage-feedback topology
• Low offset voltage = 200µV
• Low bias current = 2µA
• Low offset current = 0.1µA
• Output current = 50mA over temperature
• Fast settling = 13ns to 0.1%
Applications
• Active filters/integrators
• High-speed signal processing
• ADC/DAC buffers
• Pulse/RF amplifiers
• Pin diode receivers
• Log amplifiers
