LTC6652BHLS8-4.096

Overview

The LTC6652BHLS8-4.096 is a precision buffered voltage reference with a nominal output of 4.096V, housed in an 8-lead hermetic LS8 package. It features a maximum temperature drift of 8ppm/°C and initial accuracy of ±0.1%. The device operates over a –40°C to 125°C range with a supply voltage up to 13.2V. Key electrical parameters include low noise (2.1ppm P-P), ±5mA source/sink current capability, and shutdown current below 2µA.

Feature Summary

• High-order curvature compensation ensures predictable temperature characteristics and minimal drift.
• Hermetic 5mm × 5mm surface mount package provides outstanding stability against humidity and mechanical stress.
• Capable of sourcing and sinking current without requiring an external load capacitor for stability.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package type and lead finish. Confirm that the LS8 variant is selected for applications requiring hermetic sealing and superior long-term stability compared to plastic packages. Ensure the B-grade specifications align with the design's accuracy requirements.

Selection Notes

Select this component when high thermal stability and humidity resistance are critical. The LS8 package offers lower hysteresis and long-term drift than the MSOP version. Consider the 4.096V output for compatibility with standard ADC full-scale ranges. Evaluate power dissipation limits if operating at maximum input voltage and load currents.

Part Context

This part belongs to the LTC6652 family of precision low drift references. The LS8 designation indicates an 8-pin leadless ceramic chip carrier package, distinct from the plastic MSOP option. It shares core circuitry with other voltage options in the series but is optimized for environments demanding hermetic protection and enhanced reliability.

FAQ

Is an output capacitor required for the LTC6652BHLS8-4.096?

No, the device is stable without an output capacitor. However, a capacitor between 0.1µF and 10µF may be beneficial for specific load conditions or transient response improvements.

What is the impact of IR reflow on the LS8 package?

IR reflow can cause a slight positive mean shift in output voltage due to material expansion differences, but the overall drift remains within specified limits. The hermetic nature of the LS8 package prevents humidity-induced shifts.
