EL2074
September 26, 2001
FN7150
400MHz GBWP Gain-of-2 Stable
Operational Amplifier
The EL2074 is a precision voltage-
feedback amplifier featuring a 400MHz
gain-bandwidth product, fast settling
time, excellent differential gain and differential phase perfor-
mance, and a minimum of 50mA output current drive over
temperature.
The EL2074 is gain-of-2 stable with a -3dB bandwidth of
400MHz at A
V
= +2. It has a very low 200µV of input offset
voltage, only 2µA of input bias current, and a fully symmetri-
cal differential input. Like all voltage-feedback operational
amplifiers, the EL2074 allows the use of reactive or non-lin-
ear components in the feedback loop. This combination of
speed and versatility makes the EL2074 the ideal choice for
all op-amp applications at a noise gain of 2 or greater requir-
ing high speed and precision, including active filters,
integrators, sample-and-holds, and log amps. The low distor-
tion, high output current, and fast settling makes the EL2074
an ideal amplifier for signal-processing and digitizing
systems.
Features
• 400MHz gain-bandwidth product
• Gain-of-2 stable
• Ultra low video distortion = 0.01%/0.015° @NTSC/PAL
• 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%
• Low distortion = -55dB HD2, -70dB HD3 @20MHz, 2V
