MAX876BCPA

Overview

The MAX876BCPA is a precision voltage reference providing a fixed +10.0V output in an 8-pin SOIC package. It features a maximum initial accuracy of ±0.05% and a temperature coefficient of 20ppm/°C over the -40°C to +85°C operating range. The device draws a maximum quiescent current of 450µA, supports a wide supply voltage range from +4.5V to +18V, and includes a TRIM pin for ±6% voltage adjustment. It sources up to 10mA and sinks up to 2mA.

Feature Summary

• Provides a stable +10V reference with low power consumption and high accuracy
• Includes a dedicated TEMP pin generating an output voltage proportional to die temperature
• Features a TRIM pin allowing external adjustment of the reference voltage
• Offers excellent line and load regulation for stable operation across varying conditions

Applications

• 12-bit data-acquisition systems
• Digital multimeters
• Portable data-acquisition systems
• Low-power test equipment

Procurement Notes

Verify the specific suffix 'CPA' against official documentation, as the provided datasheet primarily lists 'E' series variants (e.g., MAX876BESA+). Confirm that the component meets RoHS compliance requirements if applicable, as older 'P' suffix packages may differ from lead-free specifications. Ensure the supplier provides valid traceability for the Analog Devices/Maxim Integrated manufacturer designation.

Selection Notes

Select this component when a fixed +10V precision reference is required for systems needing ±0.05% initial accuracy. It is suitable for applications demanding low quiescent current and a temperature-proportional output signal. Consider the 8-pin SOIC package constraints and verify that the input voltage range accommodates the system's supply rails without exceeding the maximum ratings.

Part Context

The MAX876BCPA belongs to the MAX873/MAX875/MAX876 family of low-power, low-drift precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. This series offers preset outputs of +2.5V, +5V, and +10V respectively, designed for high-accuracy analog circuits requiring minimal power consumption and stable performance over wide temperature ranges.

Replacement Considerations

Direct substitutes within the same family include MAX876AESA+ for tighter accuracy or MAX876BESA+ for equivalent performance in surface-mount packaging. Verify pin compatibility and thermal characteristics when transitioning between package types.
