The device includes a 18-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8484 offers a full 18-bit interface, a 16-bit option where data is read using two read cycles, or an 8-bit bus option using three read cycles. - High-Speed Parallel Interface - Wide Digital Supply 2.7 V to 5.25 V - 8-/16-/18-Bit Bus Transfer The ADS8484 is available in a 48-lead 7x7 QFN package and is characterized over the industrial - 40°C to 85°C temperature range.
