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 operates on a single +2.7V to +5.25V supply and features two single-ended channels with a maximum sampling rate of 108ksps. The device includes an internal track-and-hold circuit, an on-chip clock, and a fast wake-up time of 2.5µs. It utilizes a high-speed, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Power consumption is 3.2mW at full speed, dropping to 0.2µA in shutdown mode. The component is housed in an 8-pin Plastic DIP package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel single-ended operation for flexible signal acquisition
• Ultra-low power consumption with automatic power-down capabilities
• Integrated track-and-hold stage and on-chip oscillator
• Standard 3-wire serial interface for microprocessor connectivity

Analog To Digital Converters (ADC) Applications

• Battery-powered systems requiring extended operational life
• Portable data logging equipment
• Isolated data acquisition modules
• Process-control monitoring circuits
• Medical instrumentation devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BEPA confirms the -40°C to +85°C industrial temperature range and Plastic DIP packaging. Confirm RoHS compliance status as indicated in official documentation. Ensure the external reference voltage requirements are met within the specified input range. Validate pin compatibility if replacing older versions in existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual single-ended inputs are required alongside strict power constraints. The 12-bit resolution and 108ksps throughput suit moderate-speed applications. Consider the MAX145 variant if pseudo-differential input capability is preferred over single-ended channels. Ensure the system clock frequency aligns with the supported external or internal modes.

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 MAX144ACPA but differs in temperature rating and package type. Pin-compatible 10-bit versions like the MAX157 exist within the same product line. The device represents Maxim's approach to space-saving, battery-operated data conversion solutions.

Analog To Digital Converters (ADC) Replacement Considerations

MAX144AEPA: Offers identical electrical specifications but covers a wider commercial temperature range of 0°C to +70°C instead of the industrial -40°C to +85°C range.
