Texas Instruments ADS8365
The ADS8365 includes six, 16-bit, 250kSPS analog-to-digital converters (ADCs) with six fully differential input channels grouped into three pairs for high-speed simultaneous signal acquisition. This architecture provides excellent common-mode rejection of 80dB at 50kHz, 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.FEATURES
