LT6654AHS6-5#TRPBF

Voltage Reference Overview

The LT6654AHS6-5#TRPBF is a precision series voltage reference from Analog Devices, featuring a fixed 5V output. It operates within a supply range of VOUT + 0.5V to 36V and maintains an initial accuracy of ±0.05% with a temperature coefficient of 10ppm/°C. The device provides buffered output drive capable of sourcing and sinking ±10mA while maintaining low output impedance. It exhibits low noise performance of 2.2ppm P-P (0.1Hz to 10Hz) and low thermal hysteresis. Fully specified for operation across the -55°C to 125°C temperature range, it utilizes a 6-lead TSOT-23 package.

Voltage Reference Feature Summary

• High accuracy with curvature compensation providing 10ppm/°C drift and ±0.05% initial tolerance
• Buffered output stage ensures stable regulation with ±10mA source and sink current capability

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the A-grade designation matches the required 10ppm/°C temperature coefficient and ±0.05% accuracy specifications. Ensure the HS6 package variant aligns with the intended PCB footprint requirements for the 6-lead TSOT-23 form factor.

Voltage Reference Selection Notes

Select this component for applications demanding high precision over extended industrial temperature ranges. The buffered output simplifies circuit design by eliminating the need for external op-amps to drive capacitive loads or varying currents. Consider the low dropout characteristic for battery-powered or efficiency-constrained designs where input voltage margins are tight.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references designed for portable equipment and automotive environments. The family includes various output voltages and packages, such as the hermetic LS8. The AHS6 designation specifically identifies the Automotive H-grade version in the thin plastic SOT-23 package, optimized for high reliability.
