MAX144BEPA+

Analog To Digital Converters (ADC) Overview

The MAX144BEPA+ is a low-power, 12-bit successive-approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features two single-ended input channels and operates on a single supply voltage ranging from +2.7V to +5.25V. The device supports a maximum sampling rate of 108ksps with a conversion time of 7.4µs. It utilizes an internal track-and-hold circuit and offers a fast wake-up time of 2.5µs. Communication is handled via a high-speed, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The component is housed in an 8-pin Plastic DIP package and is rated for an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel single-ended operation with integrated track-and-hold functionality
• Ultra-low power consumption with automatic shutdown mode reducing current to 0.2µA
• Flexible 3-wire serial interface supporting internal or external clocking modes
• High-speed data throughput up to 108ksps with rapid 2.5µs wake-up capability

Analog To Digital Converters (ADC) Applications

• Battery-powered portable systems requiring extended operational life
• Portable data logging equipment with space constraints
• Isolated data acquisition modules in industrial environments
• Process-control monitoring circuits demanding low power draw
• Medical instrumentation and test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BEPA against official documentation to confirm the 8-pin Plastic DIP package and the -40°C to +85°C industrial temperature range. Confirm RoHS compliance status through manufacturer datasheets as regulatory requirements may vary by production batch. Ensure compatibility with existing PCB footprints for through-hole mounting before integration into new designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual single-ended inputs are required within a compact 8-pin footprint. It is suitable for applications needing moderate speed up to 108ksps with minimal power usage. Consider the MAX145 variant if pseudo-differential input configuration is preferred over single-ended channels. Evaluate source impedance requirements to ensure proper acquisition time during high-speed conversions.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX144/MAX145 family of low-power ADCs. It shares architectural similarities with the MAX157 and MAX159, which offer pin-compatible 10-bit resolution versions. The series is designed for applications balancing precision, speed, and power efficiency in small form factors.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX157 and MAX159, which provide 10-bit resolution. Verify that the reduced resolution meets system accuracy requirements before substitution.
