The LT1225 is a very high speed operational amplifier with excellent DC performance. The LT1225 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 LT1225 is a member of a family of fast, high performance amplifiers that employ advanced bipolar complementary processing.
