The AD7478ARTZ-500RL7 is a 8-bit high speed, low power successive-approximation Analog-to-digital Converter (ADC) contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 6MHz. 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 these parts. It uses advanced design techniques to achieve very low power dissipation at high throughput rates. The reference for the parts is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus, the analog input range for the part is 0V to VDD. The conversion rate is determined by the SCLK.
● Flexible power/serial clock speed management
● No pipeline delays
● High speed serial interface SPI™/QSPI™/MICROWIRE™/DSP compatible
