ANALOG DEVICES AD7477AAKSZ-500RL7 Analogue to Digital Converter, 10 bit, 1 MSPS, Single Ended, SPI, Single, 2.35 V

AD7477AAKSZ-500RL7 is a 10-bit, high-speed, low-power, successive-approximation analogue-to-digital converter (ADC). The part operates from a single 2.35V to 5.25V power supply and features throughput rates up to 1MSPS. The part contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 13MHz. 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 also initiated at this point. There are no pipeline delays associated with the parts. It is used in applications such as battery-powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, data acquisition systems, high-speed modems, and optical sensors.
