Overview
The LM4040BIX3-3.0 is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3.0 V with an initial accuracy of 0.2%. The device operates within a temperature range of -40°C to +125°C and features a maximum temperature coefficient of 70 ppm/°C. It supports a maximum shunt current of 15 mA and utilizes an SC-70-3 surface-mount package.
Feature Summary
- Provides stable, high-precision reference voltage in a compact form factor
- Operates effectively across the full industrial temperature range
- Designed for space-critical applications requiring low power consumption
Applications
- Portable battery-powered instrumentation
- Data acquisition systems
- Handheld meters
Procurement Notes
Verify the specific suffix 'IX3' against official manufacturer documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with SC-70-3 footprints during PCB layout. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a 3.0 V reference with 0.2% initial accuracy is required. It is suitable for designs needing operation up to 125°C. Compare against LM4040AIM3 variants if tighter 0.1% accuracy or lower noise is necessary. Verify that the 15 mA maximum shunt current meets the circuit's load requirements.
Part Context
This part belongs to the LM4040 family of two-terminal shunt mode bandgap voltage references. The family offers various fixed voltages including 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V. The 'B' designation indicates the 0.2% accuracy grade, while 'IX3' typically denotes the SC-70-3 package configuration.
