FEATURES - - - - - Six Input Channels Fully Differential Inputs Six Independent 16-Bit ADCs 4µs Total Throughput per Channel Low Power: 200m W in Normal Mode 5m W in Nap Mode 50µW in Power-Down Mode TQFP-64 Package Package DESCRIPTION The ADS8365 includes six, 16-bit, 250k SPS analog-to-digital converters (ADCs) with six fully differential input channels grouped into three 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 architecture provides excellent mon-mode rejection of 80d B at 50k Hz, which is important in high-noise environments. The ADS8365 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. - - - - APPLICATIONS Motor Control Multi-Axis Positioning Systems 3-Phase Power Control CH A0+ CH A0- CDAC S/H Amp p SAR HOLDA CH A1+ CH A1S/H Amp CH B0+ CH B0S/H Amp CDAC p Interface Conversion and Control CDAC p A0 A1 A2 ADD NAP RD WR CS FD EOC CLK RESET BYTE 16 SAR HOLDB CH B1+ CH B1S/H Amp CH C0+ CH C0S/H Amp SAR HOLDC CH C1+ CH C1S/H Amp REFIN REFOUT Internal 2.5V Reference CDAC p FIFO Register and 6x CDAC p Data Input/Output CDAC p Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
