LT6650HS5#TRPBF

Voltage Reference Overview

The LT6650HS5#TRPBF is a micropower, low voltage series voltage reference featuring an integrated rail-to-rail buffer amplifier. It provides a nominal 400mV output with a maximum initial accuracy of ±1.5% over the full operating temperature range of –40°C to 125°C. The device operates from supply voltages between 1.4V and 18V while drawing only 5.6µA typical supply current. It supports bidirectional current sourcing and sinking up to 200µA and ensures stability with load capacitors of 1µF or higher.

Voltage Reference Feature Summary

• Micropower operation with 5.6µA typical supply current
• Rail-to-rail buffer amplifier for bidirectional current drive
• Wide supply voltage range from 1.4V to 18V
• Low profile 5-lead TSOT-23 package

Voltage Reference Applications

• Battery-operated systems
• Handheld instruments
• Industrial control systems
• Data acquisition systems
• Negative voltage references

Voltage Reference Procurement Notes

Verify the specific HS5 suffix indicates the extended industrial temperature grade of –40°C to 125°C. Confirm the #TRPBF designation corresponds to lead-free tape and reel packaging. Ensure compatibility with the required 5-lead TSOT-23 footprint during procurement planning.

Voltage Reference Selection Notes

Select this component when a sub-volt reference is required in a compact surface-mount package. The wide input voltage range accommodates single-cell battery applications down to 1.4V. The internal buffer allows direct driving of ADC inputs without external amplification.

Voltage Reference Part Context

This part belongs to the LT6650 family of micropower voltage references. It shares the same core architecture as the CS5 and IS5 variants but offers an extended operational temperature range suitable for harsh industrial environments. The HS5 grade ensures consistent performance across the full –40°C to 125°C span.
