AD7278BRMZ

AD7278 is a high speed, low power, successive approximation analog-to-digital converter. It contain a low noise, wide bandwidth track and-hold amplifier that can handle input frequencies in excess of 55MHz. The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS, and the conversion is initiated at this point. There are no pipeline delays associated with the part. It uses an advanced design techniques to achieve very low power dissipation at high throughput rates.
