MAX675ESA+T

Overview

The MAX675ESA+T is a precision voltage reference providing a pretrimmed +5V output with ±0.15% initial accuracy and a temperature coefficient of 15ppm/°C. It operates within a -40°C to +85°C range in an 8-pin Narrow SO package. Key electrical parameters include a maximum quiescent supply current of 1400µA, line regulation of 0.01%/V, and load regulation of 0.002%/mA. The device features short-circuit protection, a 150mV adjustment range via the TRIM pin, and a dedicated TEMP pin for absolute temperature sensing.

Feature Summary

• Pretrimmed to +5V with high initial accuracy

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts due to the narrow SO footprint. Confirm that the required operating temperature range aligns with the specified industrial limits before finalizing procurement decisions.

Selection Notes

Select this component when a stable +5V reference with low drift is required. Consider the integrated temperature sensor if system monitoring is needed. Evaluate the narrow SO package constraints against available PCB space. Verify that the input voltage range supports the intended application line regulation requirements.
