LT1236AIS8-10#TRPBF

Voltage Reference Overview

The LT1236AIS8-10#TRPBF is a precision voltage reference from Analog Devices, featuring a 10V output with ±0.05% initial accuracy and a maximum temperature coefficient of 5ppm/°C. It operates within an industrial temperature range of -40°C to +85°C in an 8-lead SOIC package. The device utilizes a buried zener diode structure for low noise and high stability, supporting both series and shunt modes with up to 10mA source/sink current.

Voltage Reference Feature Summary

• Combines ultra-low drift and noise with excellent long-term stability using a buried zener diode structure
• Operates effectively in both series and shunt configurations with high input voltage immunity
• Features a dedicated trim pin for precise output voltage adjustment while maintaining temperature coefficient integrity

Voltage Reference Applications

• A/D and D/A converters
• Precision regulators
• Inertial navigation systems
• Digital voltmeters

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the AIS8 designation aligns with the required industrial temperature range (-40°C to +85°C) and SOIC-8 footprint. Cross-reference the datasheet electrical characteristics for line and load regulation limits under your specific operating conditions.

Voltage Reference Selection Notes

Select this component for applications requiring high DC accuracy and low thermal drift without active heating. The 10V output suits systems needing higher signal swings than standard 2.5V or 5V references. Ensure the minimum input-output differential of 1V is maintained for proper regulation across the full industrial temperature range.

Voltage Reference Part Context

Part of the LT1236 family of precision references based on buried zener technology. This family offers superior temperature drift and time stability compared to band-gap references. The LT1236 is pin-compatible with older AD586 and AD587 devices, facilitating upgrades in existing designs.

Voltage Reference FAQ

Can the LT1236-10 be used as a two-terminal shunt regulator?

Yes, the 10V version can function as a shunt regulator with the same precision characteristics as the three-terminal connection.

How does the trim pin affect the temperature coefficient?

The trim pin allows voltage adjustment with minimal impact on the temperature coefficient if driven from a low impedance source (≤3kΩ). Using a potentiometer requires careful selection to maintain stability.
