Overview
The MAX6350CSA+ is a precision series voltage reference with buried-zener technology, providing a fixed 5V output. It features an initial accuracy of ±0.02% and a maximum temperature coefficient of 1ppm/°C. The device operates within an input voltage range of 8V to 36V and supports load currents up to ±15mA. Noise performance includes 3µVp-p (0.1Hz to 10Hz) and 2.5µVrms (10Hz to 1kHz). It consumes approximately 3.3mA supply current, offers long-term stability of 30ppm/1000hr, and is housed in an 8-pin SO package.
Feature Summary
- Utilizes buried-zener technology for low-noise performance
- Provides optional external trimming and noise reduction capabilities
- Maintains stability across all capacitive loads
Applications
- High-resolution analog-to-digital converters
- Digital-to-analog converters
- High-accuracy industrial and process control systems
- Precision current sources
Procurement Notes
Verify the specific suffix 'CSA+' against official documentation to confirm the 8-pin SO package and 0°C to +70°C operating temperature range. Ensure compatibility with required line regulation and load regulation specifications for your circuit design before procurement.
Selection Notes
Select this component when high resolution up to 16 bits is required. Consider the buried-zener architecture for superior noise characteristics compared to standard bandgap references. Evaluate the need for external trimming or noise reduction features based on system sensitivity requirements.
Part Context
This part belongs to the MAX6325/MAX6341/MAX6350 family of low-noise, precision voltage references. While sharing similar internal architectures and pinouts, the MAX6350 is specifically configured for a 5V output, distinguishing it from the 2.5V MAX6325 and 4.096V MAX6341 variants.
