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
bandwidth (A
V
= +20), and 2.5ns rise/fall time, while
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.
