General Description
The EL4390C is three wideband current-mode feedback amplifi-
ers optimized for video performance, each with a DC restore
amplifier. The DC restore function is activated by a common
TTL/CMOS compatible control signal while each channel has a
separate restore reference.
# 80 MHz 3 dB bandwidth for
gains of 1 to 10
# 800 V/ms slew rate
# 15 MHz bandwidth flat to 0.1 dB
# Excellent differential gain and
phase
Each amplifier can drive a load of 150X at video signal levels.
# TTL/CMOS compatible DC

The EL4390C operates on supplies as low as 4V up to 15V.
Being a current-mode feedback design, the bandwidth stays rel-
