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.
