The MAX1029BEEP+ is a 10-bit analog-to-digital converter from Analog Devices Inc./Maxim Integrated, offering a sampling rate of 300k SPS. It features 6 or 12 multiplexed input channels and supports 3-Wire, Microwire, QSPI, and SPI interfaces for flexible digital connectivity. The MUX-S/H-ADC architecture ensures accurate conversion of multiple analog signals. This ADC is well-suited for data acquisition systems, sensor interfaces, and portable instrumentation requiring multi-channel measurement in a compact 20-SSOP package.

  • High Channel Density: Supports up to 12 input channels, reducing the need for external multiplexers and simplifying PCB layout.
  • Flexible Digital Interface: Compatible with SPI, QSPI, Microwire, and 3-Wire protocols, ensuring easy integration with a wide range of microcontrollers.
  • Fast Sampling: 300k SPS sampling rate enables real-time monitoring of rapidly changing signals in control and measurement applications.
  • Compact Package: The 20-SSOP package saves board space, ideal for space-constrained designs.

Multi-Channel Data Acquisition Systems

The 12-channel input capability combined with a 300k SPS sampling rate allows efficient digitization of multiple analog signals in industrial data acquisition systems, reducing component count.

Portable Instrumentation

With a 10-bit resolution and SPI interface, this ADC is ideal for portable measurement devices where low pin count and simple digital connectivity are required.

Sensor Signal Digitization

The integrated multiplexer enables direct connection of multiple sensors (temperature, pressure, etc.) to a single ADC, simplifying sensor interface design in monitoring systems.

Motor Control Feedback

Fast sampling at 300k SPS supports real-time current and voltage monitoring in motor control loops, enabling precise feedback for improved efficiency.

Battery-Powered Devices

The low operating temperature range and flexible interface make it suitable for battery-powered remote sensors that require periodic multi-channel readings.
