MAX1362LEUB+T

ADCs/DACs - Special Purpose Overview

The MAX1362LEUB+T is a low-power, 10-bit, 4-channel analog-to-digital converter (ADC) designed for automatic system-monitoring applications. It features a digitally programmable window comparator with an interrupt output that asserts when analog inputs exceed programmed thresholds without host interaction. The device integrates an internal 4.096V voltage reference, a clock, and a high-speed I²C-compatible serial interface supporting up to 1.7MHz. Operating from a single 4.5V to 5.5V supply, it consumes 436µA at 150ksps in monitor mode and less than 0.5µA in power-down mode. It is available in a 10-pin µMAX package.

ADCs/DACs - Special Purpose Feature Summary

• Digitally programmable window comparator with SMBus alert response for automatic fault detection
• Four configurable analog inputs supporting single-ended or fully differential operation
• Internal 4.096V voltage reference with support for external references from 1V to VDD
• High-speed I²C-compatible serial interface with standard, fast, and 1.7MHz modes

ADCs/DACs - Special Purpose Applications

• System monitoring and supervision
• Servers and workstations
• High reliability power supplies
• Medical instrumentation

ADCs/DACs - Special Purpose Procurement Notes

Verify the component matches the specific ordering suffix LEUB+T, which indicates the lead-free/RoHS-compliant version in a 10-pin µMAX package. Confirm the supply voltage requirements align with the MAX1362 specification of 4.5V to 5.5V, as the MAX1361 variant operates at 2.7V to 3.6V. Ensure the application environment stays within the specified -40°C to +85°C temperature range.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX1362 over the MAX1361 if the system operates on a 4.5V to 5.5V supply rail, as the MAX1362 includes a higher internal reference voltage of 4.096V compared to the MAX1361's 2.048V. Consider the monitor mode functionality if automatic threshold checking without host intervention is required. Verify that the 10-bit resolution and 94.4ksps throughput rate meet the dynamic performance needs of the specific analog signals being monitored.

ADCs/DACs - Special Purpose Part Context

The MAX1362 is part of the MAX1361/MAX1362 family of 4-channel, 10-bit system monitors. It shares the same pinout and functional architecture as the MAX1361 but is optimized for higher supply voltages. For applications requiring 12-bit resolution, the pin-compatible MAX1363/MAX1364 devices are available. The device utilizes successive-approximation conversion techniques with fully differential input track/hold circuitry.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX1361EUB+T is a pin-compatible alternative but requires a 2.7V to 3.6V supply and provides a 2.048V internal reference. The MAX1363/MAX1364 series offers 12-bit resolution with identical pinouts. No other direct substitutes are documented in the provided datasheet.
