NOTE: (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 of extended periods may affect device reliability.
DescriptionThe ADS8364 includes six, 16-bit, 250KHz ADCs (Analog-to-Digital converters) with 6 fully differential input channels grouped into two pairs for high-speed simultaneous signal acquisition. Inputs to the sample-and-hold amplifiers are fully differential and are maintained differential to the input of the ADC. This provides excellent common-mode rejection of 80dB at 50KHz that is important in high-noise environments. The ADS8364 offers a flexible high-speed parallel interface with a direct address mode, a cycle, and a FIFO mode. The output data for each channel is available as a 16-bit word.
