MAX1361MEUB+

Analog To Digital Converters (ADC) Overview

The MAX1361MEUB+ is a low-power, 4-channel, 10-bit analog-to-digital converter (ADC) designed for automatic system-monitoring applications. It features a digitally programmable window comparator with an interrupt output and SMBus alert response. The device integrates an internal voltage reference, clock, and a high-speed I2C-compatible serial interface supporting up to 1.7MHz. Operating from a single 2.7V to 3.6V supply, it achieves a maximum conversion rate of 94.4ksps in normal mode and 150ksps in monitor mode. Supply current is 436µA at 150ksps and reduces to less than 0.5µA in power-down mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix MEUB+ against official documentation to confirm package type and temperature range. Ensure the selected variant matches the required supply voltage specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low-power continuous monitoring with minimal host interaction. Verify that the 2.7V to 3.6V supply range aligns with the system design. Consider the integrated reference and clock capabilities if external components are to be minimized.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1361/MAX1362 family of 4-channel, 10-bit system monitors. It is pin-compatible with the MAX1363/MAX1364 series, which offer 12-bit resolution. The device is housed in a 10-pin µMAX package and operates over an extended temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1361EUB+ is a direct replacement within the same family, sharing identical specifications but differing in I2C slave address configuration.

Analog To Digital Converters (ADC) FAQ

How does the monitor mode function without host interaction?

Once configured, the monitor mode automatically asserts an interrupt when any analog input exceeds the programmed upper or lower thresholds, allowing for immediate fault detection.

What is the purpose of the SMBus alert response?

The SMBus alert response allows the host microcontroller to quickly identify which specific device caused an interrupt on a shared interrupt line.

Can the analog inputs operate in differential mode?

Yes, each of the four analog inputs is configurable for single-ended or fully differential operation, as well as unipolar or bipolar conversion modes.
