REF01CN8#PBF

Overview

The REF01CN8#PBF is a precision bandgap voltage reference providing a fixed 10V output. It operates within a supply voltage range of 12V to 40V and draws a maximum quiescent current of 1.4mA. The device guarantees an initial accuracy of ±0.3% with a typical temperature coefficient of 5ppm/°C. It features low noise performance, specified at 3ppm peak-to-peak in the 0.1Hz to 10Hz bandwidth. The component supports a load current up to 10mA and includes short-circuit protection. It is housed in an 8-lead plastic DIP package and is rated for operation between 0°C and +70°C.

Feature Summary

• Provides stable 10V reference output with high line and load regulation
• Features low temperature drift for consistent performance across operating ranges
• Includes internal short-circuit protection for robust operation

Applications

• A/D and D/A converters
• Precision regulators
• Constant current sources
• V/F converters
• Bridge excitation

Procurement Notes

Verify the specific suffix CN8 corresponds to the 8-lead plastic DIP package and the 0°C to +70°C commercial temperature grade. Confirm that the #PBF designation indicates lead-free finish compliance. Ensure the source documentation explicitly lists this part number as available from Analog Devices or authorized distributors before proceeding with procurement.

Selection Notes

Select this component when a fixed 10V reference is required with moderate accuracy and low power consumption. It is suitable for applications where low drift and low cost are primary considerations. For higher accuracy or lower drift requirements, consider the LT1019 or LT1021 series. Verify that the 10mA load current capability meets the circuit demands.

Part Context

The REF01CN8#PBF belongs to the REF-01/REF-02 family of precision voltage references manufactured by Analog Devices. This family utilizes bandgap technology to deliver stable outputs over wide operating conditions. The REF-01 variant specifically provides a 10V output, while the REF-02 provides 5V. These devices are designed for applications requiring reliable reference voltages with minimal temperature dependence.
