Overview
The MAX6341CPA is a buried-zener voltage reference providing a fixed 4.096V output in an 8-pin plastic DIP package. It operates within an input voltage range of 8V to 36V and supports ±15mA source/sink currents with a typical supply current of 3.2mA. The device features a maximum temperature coefficient of 1ppm/°C, ±0.02% initial accuracy, and low noise performance (2.4µVp-p from 0.1Hz to 10Hz). Designed for commercial temperatures (0°C to +70°C), it offers excellent line and load regulation suitable for high-resolution data conversion systems.
Feature Summary
- Utilizes buried-zener technology for ultra-low noise performance
- Provides industry-standard pinout with optional external trimming and noise reduction capabilities
- Guarantees stable operation for all capacitive loads up to 100µF
Applications
- High-Resolution Analog-to-Digital and Digital-to-Analog Converters
- High-Accuracy Reference Standard
- Precision Current Sources
Procurement Notes
Verify the specific suffix 'CPA' confirms the Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm that the component is sourced as a discontinued or obsolete part if applicable, as availability may be limited. Ensure the ordering information matches the required temperature coefficient and accuracy specifications for the design.
Selection Notes
Select this component when a fixed 4.096V precision reference is required with minimal temperature drift. The buried-zener architecture ensures superior low-frequency noise characteristics compared to bandgap references. Verify that the 8V minimum input voltage requirement aligns with the system power supply rails.
Part Context
This device belongs to the MAX6325/MAX6341/MAX6350 family of low-noise, precision voltage references. While sharing identical electrical characteristics and pinouts, the family differentiates by output voltage: 2.5V (MAX6325), 4.096V (MAX6341), and 5V (MAX6350). All variants utilize the same low-power temperature-compensation scheme.
Replacement Considerations
Direct functional substitutes within the same family include MAX6325CPA (2.5V) and MAX6350CPA (5V). Other packages such as MAX6341CSA (SOIC) offer identical electrical performance in surface-mount form factors.
