The OPA603 is a high-speed current-feedback op amp
with guaranteed specifications at both
±5V
and
±15V
power supplies. It can deliver full
±10V
signals into
150Ω loads with up to 1000V/µs slew rate. This
allows it to drive terminated 75Ω cables. With 150mA
peak output current capability it is suitable for driving
load capacitance or long lines at high speed.
In contrast with conventional op amps, the current-
feedback approach provides nearly constant band-
width and settling time over a wide range of closed-
loop voltage gains.
The OPA603 is available in a plastic 8-pin DIP and
SO-16 surface-mount packages, specified over the
industrial temperature range.
