Product Summary

The AD7490BRUZ is a 12-bit high speed, low power, 16-channel,successive-approximation ADC. The AD7490BRUZ operates from a single2.7 V to 5.25 V power supply and features throughput rates upto 1 MSPS. The AD7490BRUZ contains a low noise, wide bandwidthtrack-and-hold amplifier that can handle input frequencies inexcess of 1 MHz. The AD7490BRUZ uses advanced design techniques to achieve very low power dissipation at high throughput rates.
