TPR3340-S3TR-S

Overview

The TPR3340-S3TR-S 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 features high initial accuracy with a maximum tolerance of ±0.15% and a temperature coefficient of 30 ppm/°C across the −40°C to +125°C operating range. The device operates on a supply voltage between 2.1 V and 5.5 V, drawing a quiescent current of 180 μA. It exhibits low output noise of 80 μVpp (0.1 Hz to 10 Hz) and supports capacitive loads from 0.1 μF to 10 μF.

Feature Summary

• Delivers a precise 4.096 V fixed output with guaranteed stability over extended industrial temperature ranges.
• Maintains high accuracy through tight initial tolerance limits and minimal drift characteristics.
• Operates efficiently with low quiescent current consumption suitable for power-sensitive designs.
• Ensures stable performance with standard capacitive load requirements without external compensation.

Applications

• Precision instrumentation systems requiring stable reference voltages
• Industrial control circuits demanding wide temperature operation
• Data acquisition systems utilizing analog-to-digital converters

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 the R3F identifier listed in the official documentation. Ensure compliance with RoHS standards and halogen-free requirements as defined by the manufacturer's green product specifications before finalizing procurement orders.

Selection Notes

Select this component when a 4.096 V reference is required within the TPR33 family. Consider the ±0.15% initial accuracy and 30 ppm/°C temperature coefficient for applications needing high precision. Verify that the input voltage range of 2.1 V to 5.5 V aligns with the system power supply constraints and that the 180 μA quiescent current fits the power budget.

Part Context

This part belongs to the TPR33 series of voltage references manufactured by 3PEAK. The series includes various fixed output voltages such as 1.25 V, 2.5 V, and 3.3 V, all sharing similar electrical characteristics and packaging options. The TPR3340 specifically provides the 4.096 V option within this lineup, designed for general-purpose precision applications.

Replacement Considerations

Direct substitutes within the same family include other TPR33xx variants with different output voltages if the voltage level can be adjusted or if a different reference is needed. Cross-referencing with other manufacturers requires verifying pin compatibility and ensuring equivalent accuracy and temperature coefficients are met.
