The AD7634BSTZ is a 18-bit charge redistribution successive approximation register (SAR), architecture Analog-to-digital Converter (ADC) fabricated on Analog Devices Inc, iCMOS high voltage process. The device is configured through hardware or via a dedicated write-only serial configuration port for input range and operating mode. The AD7634 contains a high speed 18-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits and both serial and parallel system interface ports. A falling edge on CNVST samples the fully differential analog inputs on IN+ and IN-. The AD7634 features four different analog input ranges and three different sampling modes.
● Pins or serial SPI®-compatible input ranges/mode selection
● iCMOS™ process technology
● No pipeline delay
● SPI™/QSPI™/MICROWIRE™/DSP compatible
