REF3233AMDBVREP

Overview

The REF3233AMDBVREP is a micropower, precision series voltage reference from Texas Instruments, designed for military and enhanced performance applications. It delivers a fixed output of 3.3 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2.098 V to 5.5 V and draws a typical supply current of 100 µA. It features a low temperature coefficient of 4 ppm/°C and supports a maximum load current of 10 mA. Housed in a compact SOT-23-6 surface-mount package, it functions reliably across an extended industrial temperature range of -55°C to +125°C.

Feature Summary

• Military-grade reliability with enhanced specifications for harsh environments
• High precision stability with ±0.2% initial accuracy and 4 ppm/°C temperature coefficient
• Ultra-low power consumption suitable for battery-operated systems
• Rail-to-rail operation capability with wide input voltage flexibility

Applications

• Military instrumentation and avionics systems
• Portable medical devices requiring high precision
• Industrial data acquisition and sensor interfaces
• Battery-powered measurement equipment

Procurement Notes

Verify the specific suffix 'REP' indicates the required military or enhanced reliability grade during procurement. Confirm that the SOT-23-6 package aligns with PCB footprint constraints. Ensure the fixed 3.3 V output matches system requirements as adjustment is not possible. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when fixed precision references are needed without external trimming. The 10 mA output current allows driving moderate loads directly. Consider the 4 ppm/°C drift for long-term stability needs. The SOT-23-6 form factor aids in space-constrained designs compared to larger packages.

Part Context

This part belongs to the REF32xx-EP family of precision voltage references. It shares architectural similarities with other members like the REF3220 but provides a specific 3.3 V nominal output. The 'A' designation typically denotes an extended temperature range variant within the series.

Replacement Considerations

Direct substitutes include REF3233AIDBVR for commercial grade applications. For equivalent military specs, verify availability of REF3233AMDBVT. Cross-reference pinouts and thermal characteristics before substitution.
