General Description
The EL2160C is a current feedback operational amplifier with
b
3 dB bandwidth of 130 MHz at a gain ofa2. Built using the
Elantec proprietary monolithic complementary bipolar process,
this amplifer uses current mode feedback to achieve more bandwidth at a given gain than a conventional voltage feedback operational amplifier.
The EL2160C is designed to drive a double terminated 75X coax
cable to video levels. Differential gain and phase are excellent
when driving both loads of 500X (
k
0.01%/k0.01§) and double
terminated 75X cables (0.025%/0.1
§
).
The amplifier can operate on any supply voltage from 4V
(
g
2V) to 33V (g16.5V), yet consume only 8.5 mA at any supply 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 applicable quality specifications. See the Elantec document, QRA-2:

Important Note:
All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually
performed during production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test
equipment, specifically the LTX77 Series system. Unless otherwise noted, all tests are pulsed tests, therefore T
