AD7277BRMZ

AD7277BRMZ is a 10bit, high-speed, low-power, successive approximation analogue-to-digital converter (ADC). It operates from a single 2.35V to 3.6V power supply and features throughput rates of up to 3MSPS. The parts contain a low noise, wide bandwidth track and hold amplifier that can handle input frequencies over 55MHz. The conversion process and data acquisition are controlled using active-low CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of active-low CS, and the conversion is initiated at this point. There are no pipeline delays associated with the part. It uses advanced design techniques to achieve very low power dissipation at high throughput rates.
