MAX128BEAI+T

ADCs/DACs - Special Purpose Overview

The MAX128BEAI+T is a specialized data acquisition system (DAS) featuring an 8-channel, 12-bit analog-to-digital converter (ADC). Manufactured by Analog Devices Inc./Maxim Integrated, it operates on a single +5V supply and supports sampling rates up to 8 kS/s. The device integrates an internal reference voltage and utilizes a serial interface for communication. It is housed in a 28-lead SSOP package and is designed for industrial applications requiring multi-range input capabilities with fault protection.

ADCs/DACs - Special Purpose Feature Summary

• 8-channel multiplexed input with 12-bit resolution
• Serial interface compatible with standard microprocessors
• Internal reference voltage eliminates external components
• Single +5V power supply operation

ADCs/DACs - Special Purpose Applications

• Industrial process control systems
• Data acquisition modules
• Remote I/O stations
• Battery-powered instrumentation

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX127/MAX128 family of multirange data acquisition systems. It shares architectural similarities with the MAX127 but provides eight channels instead of four. The 'B' suffix typically denotes a specific temperature range or performance grade within the Maxim Integrated product line, while 'EAI' indicates the SSOP-28 package and commercial/industrial temperature rating.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX127BCAI+T for 4-channel applications, though channel count differs. For higher channel counts, the MAX198 series offers parallel interfaces. Verify that the target application can accommodate the serial interface timing requirements if substituting with parallel ADCs.
