MAX675CSA+T

Overview

The MAX675CSA+T is a precision voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a pretrimmed +5V output with an initial tolerance of ±7mV and a temperature coefficient of 12ppm/°C. The device operates within a supply voltage range up to 33V, drawing a maximum quiescent current of 1400µA. It features short-circuit protection and includes a trim terminal for output adjustment over a ±150mV range. A dedicated TEMP pin outputs a voltage proportional to absolute temperature at approximately 2.1mV/°C. The component is housed in an 8-pin Narrow SO package and functions within an operating temperature range of 0°C to +70°C.

Procurement Notes

Verify the specific suffix CSA+T against the manufacturer's official documentation to confirm the narrow SOIC-8 package and commercial temperature grade (0°C to +70°C). Ensure compatibility with system requirements regarding the 12ppm/°C temperature coefficient and 1400µA maximum supply current. Confirm that the ordering information matches the intended application environment before procurement.

Selection Notes

Select this component when a stable +5V reference with high accuracy is required. The inclusion of a trim terminal allows for fine-tuning the output voltage to compensate for system errors. The presence of a temperature-sensing pin enables integrated thermal monitoring or compensation circuits. Verify that the load regulation and line regulation specifications meet the precision requirements of the target analog interface design.
