120MHz Current Feedback Amplifier

the Elantec monolithic Complementary Bipolar process, this

amplifier uses current mode feedback to achieve more

bandwidth at a given gain than a conventional voltage

feedback operational amplifier.

Due to its wide operating supply range (±15V) and extremely

high slew rate of 2000V/µs, the EL2030 drives ±10V into

200Ω at a frequency of 30MHz, while achieving 110MHz of

small signal bandwidth at A

95MHz for a gain of +10. On ±5V supplies the amplifier

maintains a 90MHz bandwidth for A

unity gain buffer, the EL2030 has a 120MHz bandwidth with

the gain precision and low distortion of closed loop buffers.

The EL2030 features extremely low differential gain and

phase, a low noise topology that reduces noise by a factor of

2 over competing amplifiers, and settling time of 40ns to

0.25% for a 10V step. The output is short circuit protected. In

addition, datasheet limits are guaranteed for ±5V and ±15V

supplies.

Elantec's products and facilities comply with applicable

quality specifications. See Elantec document, QRA-1:

Processing, Monolithic Integrated Circuits.
