Product Details
The AD7911/AD7921 are 10-bit and 12-bit, high speed, low power, 2-channel, successive-approxima
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 also initiated at this point. There are no pipeline delays associated with the part.
The channel to be converted is selected through the DIN pin and the mode of operation is controlled by CS . The serial data stream from the DOUT pin has a channel identifier bit, which provides information about the channel converted.
The AD7911/AD7921 use advanced design techniques to achieve very low power dissipation at high throughput rates.
The reference for the part is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus the analog input range for the part is 0 to VDD.
The conversion rate is determined by the SCLK.
