LTC6652AHLS8-5#PBF

Overview

The LTC6652AHLS8-5#PBF is a precision buffered voltage reference with a fixed 5V output, housed in an 8-lead hermetic LS8 package. It features high accuracy of ±0.05% and a maximum temperature coefficient of 5ppm/°C over the –40°C to 125°C range. The device supports a supply voltage up to 13.2V with a minimum dropout of 300mV. It provides ±5mA source/sink current capability, low noise of 2.1ppm P-P (0.1Hz to 10Hz), and includes a shutdown mode consuming less than 2µA.

Feature Summary

• High-order curvature compensation ensures predictable temperature characteristics and minimal drift.
• Hermetic 5mm × 5mm LS8 package provides outstanding stability and immunity to humidity effects.
• Capable of sourcing and sinking 5mA load current without requiring an external output capacitor.

Applications

• Automotive control and monitoring systems
• High-resolution data acquisition systems
• Precision regulators and instrumentation

Procurement Notes

Verify the LS8 package designation against the specific MSOP variant requirements. Confirm that the A-grade accuracy and 5ppm/°C drift specifications align with the design tolerance. Ensure the hermetic package availability matches the environmental constraints of the target application.

Selection Notes

Select this part for applications demanding superior long-term stability and humidity resistance compared to plastic packages. The LS8 package is suitable for harsh environments where hermeticity is critical. Verify that the 5V output level meets the system reference needs and that the 13.2V maximum input rating accommodates the supply rail.

Part Context

This component belongs to the LTC6652 family of precision references, which are fully specified from –40°C to 125°C. The LS8 package variant offers improved thermal hysteresis and long-term drift performance compared to the standard MSOP version, making it ideal for high-reliability industrial and automotive uses.
