EL2166C
110 MHz Current Feedback Amplifier with Disable
Features
110 MHz 3 dB bandwidth (AV e a 2) 115 MHz 3 dB bandwidth (AV e a 1) R01% differential gain 0 L e 500X R01 differential phase 0 L e 500X Low supply current 7 5 mA Fast disable k 75 ns Low cost 1500 V ms slew rate
General Description
The EL2166C is a current feedback operational amplifier with b 3 dB bandwidth of 110 MHz at a gain of a 2 Built using the t Elantec proprietary monolithic complementary bipolar process his amplifer uses current mode feedback to achieve more bandwidth at a given gain than a conventional voltage feedback opT erational amplifier he EL2166C 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% k 0 01 ) and double terminated 75X cables (0 025% 0 05 0 VS e g 15V 0 04% T 02 VS e g 5V) he EL2166C has a superior output disable function Time to enable or disable is k 75 ns The DISABLE pin is TTL CMOS compatible In disable mode the amplifier can withstand over 1500 V ms signals at their outputs The amplifier can operate on any supply voltage from 10V ( g 5V) to 33V ( g 16 5V) yet consume only 7 5 mA at any supply voltage The EL2166C is availC le in 8-pin P-DIP and 8-pin SO packages ab
