Overview
The MAX6250BCSA-T is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed 5.000V output with ±0.1% initial accuracy and a maximum temperature coefficient of 5ppm/°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 3.3mA and is housed in an 8-pin SO package.
Feature Summary
- Buried-zener technology for lowest noise performance
- External trimming capability via TRIM pin
- Optional noise reduction via NR pin
- Stable operation with all capacitive loads
Applications
- High-resolution analog-to-digital converters
- Digital-to-analog converters
- High-accuracy industrial process control systems
- Precision current sources
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the BC grade corresponds to the required 5ppm/°C temperature coefficient and ±0.1% accuracy specifications for your application. Ensure compatibility with the 8-SOIC footprint during PCB layout.
Selection Notes
Select this part for applications requiring high stability and low noise without the power consumption of heated references. The buried-zener architecture ensures excellent long-term stability. Consider the external trim option if tighter tolerance than the factory-set value is necessary for the system design.
Part Context
This component belongs to the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. While sharing similar internal architectures and features, the MAX6250 variant is specifically configured for a 5.000V output, distinguishing it from the 2.5V and 4.096V options within the same series.
