The LT1224 is a very high speed operational amplifier with
excellent DC performance. The LT1224 features reduced
input offset voltage and higher DC gain than devices with
comparable bandwidth and slew rate. The circuit is a
single gain stage with outstanding settling characteristics.
The fast settling time makes the circuit an ideal choice for
data acquisition systems. The output is capable of driving
a 500Ω load to
±12V
with
±15V
supplies and a 150Ω load
to
±3V
on
±5V
supplies. The circuit is also capable of
driving large capacitive loads which makes it useful in
buffer or cable driver applications.
The LT1224 is a member of a family of fast, high per-
formance amplifiers that employ Linear Technology
Corporation’s advanced bipolar complementary
processing.
