The ADAS1135JBCZ is a 24-bit, 256-channel analog-to-digital converter from Analog Devices, specifically engineered for high-channel-count data acquisition systems. It samples at 22.6k SPS per channel, using a sample-and-hold architecture to ensure simultaneous capture across all inputs. With LVDS and SPI interfaces, it supports high-speed data transfer to processors. The device operates with external or internal references and is packaged in a 324-BGA, making it ideal for medical imaging, particle physics, and industrial sensor arrays.

  • 256 Simultaneous Channels: Enables parallel sampling of large sensor arrays, reducing system latency and improving throughput.
  • 24-bit Precision: Provides exceptional dynamic range, ideal for low-amplitude signal detection in medical and scientific instruments.
  • LVDS Interface: High-speed serial output minimizes pin count and supports long-distance data transmission.
  • Flexible Reference Options: Supports both external and internal references, allowing optimization for accuracy or simplicity.
