The AD7866ARUZ is a dual 12-bit high speed, low power successive approximation Analog-to-digital Converter (ADC) operates from a single 2.7 to 5.25V power supply and features throughput rates up to 1MSPS. The device contains two ADCs, each preceded by a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 10MHz. The conversion process and data acquisition are controlled using standard control inputs, allowing easy interfacing to microprocessors or DSPs. The input signal is sampled on the falling edge of CS, conversion is also initiated at this point. The conversion time is determined by the SCLK frequency. There are no pipelined delays associated with the part. It uses advanced design techniques to achieve very low power dissipation at high throughput rates. The part offers flexible power/throughput rate management when operating in sleep mode. Each on-board ADC can also be supplied with a separate individual external reference.
● Flexible power/throughput rate management
● Simultaneous conversion/read
● No pipeline delays
● High speed serial interface SPI™/QSPI™/MICROWIRE™/DSP compatible
