LM4041CIZ-1.2/NOPB

Overview

The LM4041CIZ-1.2/NOPB is a precision shunt voltage reference from Texas Instruments, offering a fixed nominal output of 1.225V. It features an initial accuracy of ±0.5% and a temperature coefficient of 100 ppm/°C. The device operates within a wide current range of 45µA to 12mA and maintains stability across all capacitive loads without requiring external output capacitors. It is housed in a compact SC-70-5 surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

Provides stable reference voltage with low dynamic impedance and low noise characteristics
Operates stably with any capacitive load without requiring external output capacitors
Utilizes Zener-zap reverse breakdown voltage trimming for precise factory calibration

Applications

Portable battery-powered equipment requiring low quiescent current
Precision analog-to-digital converter (ADC) reference sources
Data acquisition systems requiring stable voltage references
Temperature sensing circuits utilizing reference voltage stability

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C). Confirm the 'Z' designation corresponds to the SC-70-5 package variant. Ensure the '-NOPB' suffix confirms lead-free and RoHS compliance status as per manufacturer specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 1.225V reference with ±0.5% accuracy is required in a small SC-70-5 footprint. It is suitable for applications needing operation down to 45µA cathode current. Choose over adjustable variants if a fixed voltage is sufficient. Consider the AEC-Q100 qualified versions if automotive reliability standards are mandatory for the design.

Part Context

This part belongs to the LM4041 family of micropower precision shunt voltage references. The family includes both fixed and adjustable output options across various packages like SOT-23 and TO-92. The LM4041 series is designed for cost-effective solutions in portable electronics, offering high precision through internal trimming processes while maintaining low power consumption profiles.
