General Description
The EL2160C is a current feedback operational amplifier with
b
3 dB bandwidth of 130 MHz at a gain of
a
2 Built using the
Elantec proprietary monolithic complementary bipolar process
this amplifer uses current mode feedback to achieve more band-
width at a given gain than a conventional voltage feedback op-
erational amplifier
The EL2160C is designed to drive a double terminated 75
X coax
cable to video levels Differential gain and phase are excellent
when driving both loads of 500
X (
k
0 01%
k
0 01 ) and double
terminated 75
X cables (0 025% 0 1 )
The amplifier can operate on any supply voltage from 4V
(
g
2V) to 33V (
g
16 5V) yet consume only 8 5 mA at any sup-
ply voltage Using industry standard pinouts the EL2160C is
available in 8-pin P-DIP and 8-pin SO packages For dual and
quad applications please see the EL2260C EL2460C datasheet
Elantec's facilities comply with MIL-I-45208A and offer appli-
cable quality specifications See the Elantec document QRA-2
