LT1208 - Dual and Quad 45MHz, 400V/µs Op Amps

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 ohms load to ±12V with ±15V supplies and a 150 ohms load to ±3V on ±5V supplies. The amplifiers are also capable of driving large capacitive loads which make them useful in buffer or cable driver applications. The LT1208/LT1209 are members of a family of fast, high performance amplifiers that employ Linear Technology Corporation’s advanced bipolar complementary processing.
