These amplifiers combine very low noise and supply current with a 215MHz gainbandwidth product, a 70V/µs slew rate and are optimized for low supply voltage signal conditioning systems. The LT6230-10 is a single amplifier optimized for higher gain applications resulting in higher gain bandwidth and slew rate. The LT6230 and LT6230-10 include an enable pin that can be used to reduce the supply current to less than 10µA. The amplifier family has an output that swings within 50mV of either...
