LT1236ACN8-10#PBF

Voltage Reference Overview

The LT1236ACN8-10#PBF is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 10 V with an initial accuracy of ±0.05%. The device features a temperature coefficient of 5 ppm/°C and operates within an industrial temperature range of 0°C to +70°C. It supports a maximum series input voltage of 40 V and handles a maximum shunt current of 10 mA. The typical operating supply current is 800 µA, with a maximum power supply current of 1.5 mA. The minimum shunt current required for regulation is 1.1 mA. The component is housed in an 8-pin PDIP package designed for through-hole mounting.

Voltage Reference Feature Summary

• Utilizes a buried Zener diode structure to achieve low noise and superior long-term stability compared to surface breakdown devices.
• Capable of both sourcing and sinking up to 10 mA of current while maintaining high precision.
• Designed to minimize thermal regulation effects and temperature-induced hysteresis without requiring high-power on-chip heaters.

Voltage Reference Applications

• High-precision data acquisition systems
• Calibration equipment requiring stable reference voltages
• Industrial process control instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix ACN8-10#PBF against the official Analog Devices datasheet to confirm the package type (PDIP), temperature grade (C), and voltage output (10V). Ensure compatibility with through-hole assembly processes. Check for restricted availability status as indicated by distributor listings. Confirm RoHS compliance details directly from the manufacturer's documentation before procurement.

Voltage Reference Selection Notes

Select this component when a through-hole 10V reference with ±0.05% initial accuracy and 5 ppm/°C drift is required. It serves as a drop-in replacement for legacy parts like the AD586 and AD587 due to pin compatibility. Consider the 800 µA typical quiescent current and 10 mA load capability for power budgeting. Verify that the 0°C to +70°C operating range meets the environmental requirements of the target application.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision voltage references from Analog Devices. The family includes variants with different accuracies, temperature coefficients, and packages such as SOIC and DIP. The LT1236 series is characterized by its use of a sub-surface Zener structure, offering better time stability than standard bandgap references. This specific model represents the commercial grade version in an 8-pin PDIP package.
