TPR5040-SO1R

Overview

The TPR5040-SO1R is a high-precision voltage reference from the TPR50 series, manufactured by 3PEAK. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.05%. The device operates within a supply voltage range of 3 V to 15 V and supports both sourcing and sinking currents up to ±10 mA. It features a low temperature coefficient of 2.5 ppm/°C typical over the full operating range and exhibits low noise characteristics. The component is housed in an 8-pin SOP package and is rated for operation across a temperature range of -40°C to +125°C.

Feature Summary

• High precision with 0.05% maximum initial accuracy
• Low temperature drift performance suitable for stable references
• Capable of supporting bidirectional current flow of ±10 mA
• Includes a dedicated noise reduction pin for enhanced signal integrity

Applications

• Battery test equipment
• Industrial control systems
• Precision instrumentation
• Medical equipment

Procurement Notes

Verify the specific part number suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure that the ordering information matches the required output voltage and thermal characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly processes.

Selection Notes

Select this component when a stable 4.096 V reference is required with high initial accuracy and low temperature drift. Consider the ±10 mA output capability for driving moderate loads without external buffering. Evaluate the SOP8 package dimensions for PCB layout constraints and verify that the input voltage range accommodates the system supply variations.

Part Context

The TPR5040-SO1R belongs to the TPR50 family of low-noise, low-drift precision voltage references produced by 3PEAK. This series offers multiple fixed output voltages and package options, including SOP8 and MSOP8. The family is designed for applications demanding high resolution and stability, providing consistent performance across wide temperature ranges.

Replacement Considerations

Compatible alternatives within the same product line include TPR5040-VS1R-S, which utilizes an MSOP8 package instead of SOP8 while maintaining identical electrical specifications.
