LT6654AHLS8-2.048

Voltage Reference Overview

The LT6654AHLS8-2.048 is a precision series voltage reference in an 8-lead hermetic LS8 package, delivering a fixed 2.048V output with ±0.05% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It supports input voltages up to 36V, operates from –40°C to +125°C, and provides ±10mA drive current. Key specifications include 1.6ppm P-P noise (0.1Hz to 10Hz), 15ppm hysteresis, and 15ppm/√kHr long-term drift.

Voltage Reference Feature Summary

• Hermetic 5mm × 5mm LS8 package ensures outstanding stability and low thermal hysteresis.
• Advanced curvature compensation provides high accuracy and low drift.
• Buffered output enables ±10mA sourcing and sinking with low output impedance.

Voltage Reference Applications

• High resolution data acquisition systems
• Automotive control and monitoring
• High temperature industrial sensing
• Precision regulators

Voltage Reference Procurement Notes

Verify the specific LS8 package variant against the datasheet ordering information table. Confirm that the A-grade designation matches the required 10ppm/°C temperature coefficient and ±0.05% accuracy limits for the target application environment.

Voltage Reference Selection Notes

Select this part for applications requiring superior long-term stability and low hysteresis compared to plastic packages. The LS8 package is suitable for harsh environments where hermetic sealing and minimal thermal stress effects are critical for maintaining precision over time.

Voltage Reference Part Context

This component belongs to the LT6654 family of wide supply, low noise references. While other variants use SOT-23 packages, the AHLS8 suffix indicates the A-grade specification within the hermetic 8-lead leadless chip carrier format, optimized for automotive and high-reliability industrial uses.
