TPR3340-S3TR

Overview

The TPR3340-S3TR is a fixed-output voltage reference from the 3PEAK TPR33 series, providing a nominal output of 4.096 V in an SOT23G-3 package. It operates within a supply voltage range of 2.1 V to 5.5 V and maintains high accuracy with an initial tolerance of ±0.15% and a temperature coefficient of 30 ppm/°C across the −40°C to 125°C operating range. The device draws a quiescent current of 180 μA and exhibits low noise characteristics, specifically 80 μVpp in the 0.1 Hz to 10 Hz frequency band. It supports capacitive loads between 0.1 μF and 10 μF without stability issues.

Feature Summary

• Delivers a precise 4.096 V fixed output with guaranteed initial accuracy of ±0.15% and extended temperature stability.
• Features ultra-low noise performance of 80 μVpp in the 0.1 Hz to 10 Hz bandwidth for sensitive signal chain applications.
• Operates stably with capacitive loads ranging from 0.1 μF to 10 μF, simplifying external component requirements.

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converter (ADC) references
• Industrial instrumentation

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel quantity of 3,000 units. Confirm that the SOT23G-3 package marking corresponds to R3F as documented in the manufacturer's order information table. Ensure compliance with RoHS standards and halogen-free specifications before finalizing procurement orders.

Selection Notes

Select this component when a stable 4.096 V reference is required for precision measurement circuits. The wide operating temperature range makes it suitable for industrial environments. Consider the low quiescent current for battery-powered designs, while ensuring the load capacitance remains within the specified 0.1 μF to 10 μF range for optimal stability.

Part Context

This part belongs to the TPR33 family of voltage references manufactured by 3PEAK. The family includes variants with different fixed output voltages such as 1.25 V, 2.048 V, 2.5 V, 3 V, and 3.3 V, all sharing similar electrical characteristics and packaging options. The TPR33 series is designed to provide high precision and low drift for analog signal processing applications.
