(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
DescriptionThe ADS8380 is a high performance 18-bit, 600-kHz A/D converter with single-ended (pseudo-differential) input. The device includes an 18-bit capacitor-based SAR A/D converter with inherent sample and hold.The ADS8380 offers a high-speed CMOS serial interface with clock speeds up to 40 MHz.
The ADS8380 is available in a 28 lead 6 *6 QFN package and is characterized over the industrial 40°C to 85°C temperature range.
