Analog Devices LTC6228 is designed to drive the high-speed 18-bit SAR ADC (LTC2387-18). The LTC6228 is a precision and_transparent ADC driver with 0.88 nV/√Hz, 730 MHz, 500 V/µs, low distortion rail-to -rail output op amp with shutdown. The power-efficient design achieves 890 MHz while consuming only 16 mA, enabling cooler running systems. Low noise and_distortion drive an 18-bit ADC transparently without adding significant errors. With high speed and_fast slew rate, this op amp can achieve 10 V output swings. This makes it great for driving ADCs requiring 8 V peak-to-peak differential input levels..
