MAX6225BCSA

Overview

The MAX6225BCSA+ is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed output of 2.500V with an initial accuracy of ±0.12% and a maximum temperature coefficient of 5.0 ppm/°C. The device operates within an input voltage range of 8V to 36V and supports source/sink currents up to 15mA. It features a supply current of approximately 3mA and is housed in an 8-pin SO package. The component is designed for operation between 0°C and +70°C.

Feature Summary

• Buried-zener technology ensures extremely low noise performance
• External trimming capability allows for precise output adjustment
• Capable of sourcing and sinking load currents up to 15mA
• Stable operation with capacitive loads ranging from 0μF to 100μF

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• High-accuracy industrial process control systems
• Precision digital voltmeters
• Automated test equipment

Procurement Notes

Verify the specific suffix 'CSA' corresponds to the 8-pin SO package and the 'B' grade indicates the 5.0 ppm/°C temperature coefficient limit. Confirm RoHS compliance status via the '+' designation. Ensure the operating environment remains within the specified 0°C to +70°C range to maintain guaranteed electrical characteristics.

Selection Notes

Select this component when a fixed 2.5V reference with high stability is required. The B-grade specification suits applications needing tighter thermal drift limits than the A-grade variant. Consider the external trim pin if fine-tuning is necessary. Evaluate power consumption constraints against the typical 3mA supply current draw.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. While the MAX6241 outputs 4.096V and the MAX6250 outputs 5.000V, the MAX6225 is specifically configured for 2.500V. All variants share identical pinouts, packaging options, and core architectural features like buried-zener technology.

Replacement Considerations

The MAX6225ACSA+ serves as a lower-cost alternative with a 2.0 ppm/°C temperature coefficient but slightly different accuracy specifications. Other family members include the MAX6241 and MAX6250 for different voltage requirements.
