The AD7478AARMZ is a 8-bit high speed, low power successive-approximation Analog-to-digital Converter (ADC) contain 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 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 parts. It uses advanced design techniques to achieve low power dissipation at high throughput rates. The reference for the part is taken internally from VDD to allow 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
