2GHz GBWP Gain-of-10 Stable
Operational Amplifier
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
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.

... specifications allow the EL2075 to be used in DC-sensitive applications such as difference amplifiers. Furthermore, the current noise of the EL2075 is only 3.2pA/ Hz, making it an excellent choice for high-sensitivity transimpedance amplifier configurations. Gain-Bandwidth Product The EL2075 has a gain-bandwidth product of 2GHz. For gains greater than 40, its closed-loop -3dB bandwidth is approximately equal to the gain-bandwidth product divided by the noise gain of the circuit ...

... Similarly, capacitors should be low- inductance for best performance. If possible, solder the EL2075 directly to the PC board without a socket. Even high quality sockets add parasitic capacitance and inductance which can potentially degrade performance. Because of the degradation of AC performance due to parasitics, the use of ...
