EL2166
FN7052
110MHz Current Feedback Amplifier with
Disable
The EL2166 is a current feedback
operational amplifier with -3dB
bandwidth of 110MHz at a gain of +2.
Built using the Elantec proprietary 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.
The EL2166 is designed to drive a double terminated 75Ω
coax cable to video levels. Differential gain and phase are
excellent when driving both loads of 500Ω (< 0.01%/< 0.01°)
and double terminated 75Ω cables (0.025%/0.05° @
V
S
= ±15V, 0.04%/0.02° @ V
S
= ±5V).
The EL2166 has a superior output disable function. Time to
enable or disable is < 75ns. The DISABLE pin is TTL/CMOS
compatible. In disable mode, the amplifier can withstand
over 1500V/µs signals at their outputs. The amplifier can
operate on any supply voltage from 10V (±5V) to 33V
(±16.5V), yet consume only 7.5mA at any supply voltage.
The EL2166 is available in 8-pin PDIP and 8-pin SO
packages.
