Low Noise Very High Speed Operational Amplifier

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 performance amplifiers that employ advanced bipolar complementary processing.
