EL2071, EL2171

150MHz Current Feedback Amplifier

The EL2071 and EL2171 are wide

bandwidth, fast settling monolithic

amplifiers built using an advanced

complementary bipolar process. The EL2071 has a

disable/enable feature which allows power down and analog

multiplexing. These amplifiers use current-mode feedback to

achieve more bandwidth at a given gain than conventional

operational amplifiers. Designed for closed-loop gains of ±7

to ±50, the EL2071 and EL2171 have a 150MHz - 3dB

consuming only 15mA of supply current. The EL2071

consumes only 1.5mA when disabled.

The wide 150MHz bandwidth and extremely linear phase

(0.2dB deviation from linear at 50MHz) allow superior signal

fidelity. These features make the EL2071 and EL2171

especially suited for many digital communication system

applications.

The EL2071's and EL2171's settling to 0.1% in 10ns and

ability to drive capacitive loads make them ideal in flash A/D

applications. D/A systems can also benefit from the EL2071

and EL2171, especially if linearity and drive levels are

important.

Elantec products and facilities comply with MIL-I-45208A,

and other applicable quality specifications. For information
