45MHz Gain-Bandwidth
The LT1208/LT1209 are dual and quad very high speed
operational amplifiers with excellent DC performance. The
LT1208/LT1209 feature reduced input offset voltage and
higher DC gain than devices with comparable bandwidth
and slew rate. Each amplifier is a single gain stage with
outstanding settling characteristics. The fast settling time
makes the circuit an ideal choice for data acquisition
systems. Each output is capable of driving a 500

The l denotes the specifications which apply over the full operating
temperature range.
Note 1: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 2: Input offset voltage is tested with automated test equipment and is
exclusive of warm-up drift.
Note 3: Slew rate is measured in a gain of – 2. For ± 15V supplies measure
between ± 10V on the output with ± 6V on the input. For ± 5V supplies
measure between ± 2V on the output with ± 1.75V on the input.
Note 4: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2 p V P .
