The MAX11111ATB+T from Analog Devices is an 8-bit, 2-channel analog-to-digital converter with an exceptional sampling rate of 3M SPS. Its multiplexed sample-and-hold architecture enables fast sequential conversion of two inputs. The SPI interface ensures high-speed data transfer. With an external reference for precision, it operates over a wide temperature range. Packaged in a 10-WFDFN with exposed pad, it is designed for high-performance applications like radar, medical imaging, and industrial automation.

  • Extreme Speed: 3M SPS sampling rate for ultra-fast signal conversion.
  • Dual-Channel Input: Multiplexed 2-channel design for versatile signal routing.
  • Wide Temperature Range: -40°C to 125°C for automotive and industrial use.
  • External Reference: Allows precise, ratiometric measurements.
  • Compact WFDFN Package: Exposed pad enhances thermal performance in dense designs.

High-Speed Data Acquisition

The 3M SPS sampling rate and 8-bit resolution make it perfect for high-throughput DAQ systems in test and measurement equipment.

Radar and Communication Systems

In IF (intermediate frequency) sampling applications, the fast conversion rate allows digitization of wideband signals for software-defined radio.

Automotive ADAS Sensors

With a -40°C to 125°C range and 2-channel MUX, it can process signals from multiple radar or camera sensors in advanced driver-assistance systems.

Industrial High-Speed Sorting

In optical sorting machines, the 3M SPS rate enables rapid pixel-level analysis for real-time object detection and classification.

Medical Ultrasound

The high-speed sampling is suitable for digitizing ultrasound transducer arrays, improving image resolution in diagnostic equipment.

Power Electronics Control

In switch-mode power supplies, the fast ADC can monitor voltage and current in real-time for digital loop control, improving transient response.
