  • ADS8364  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device. 
  • THS4521  -  1.14mA, rail to rail O/P fully differential ADC driver

Description

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. Inputs to the sample-and-hold amplifiers are fully differential and are maintained differential to the input of the ADC. 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. The output data for each channel is available as a 16-bit word.
