LT1226
Low Noise Very High Speed
Operational Amplifier
DESCRIPTIO
The LT1226 is a low noise, very high speed operational
amplifier with excellent DC performance. The LT1226
features low input offset voltage and high DC gain. 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 LT1226 is a member of a family of fast, high per-
formance amplifiers that employ Linear Technology
Corporation’s advanced bipolar complementary
processing.
