LT1389BCS8-1.25#PBF

Voltage Reference Overview

The LT1389BCS8-1.25#PBF is a nanopower precision shunt voltage reference manufactured by Analog Devices Inc., housed in an 8-lead plastic SO (SO-8) package. It provides a fixed output voltage of 1.25V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 20ppm/°C over the operating range. The device maintains regulation at an ultralow operating current of 800nA, featuring less than 1Ω dynamic impedance and low temperature cycling hysteresis. It operates within a temperature range of 0°C to 70°C.

Voltage Reference Feature Summary

Utilizes trimmed precision thin-film resistors and improved curvature correction techniques for high stability.
Maintains voltage regulation down to an ultralow operating current of 800nA.
Features low dynamic impedance, allowing stable operation from unregulated supplies without requiring an output compensation capacitor.

Voltage Reference Applications

Portable meters
Precision regulators
A/D and D/A converters
Calibrators

Voltage Reference Procurement Notes

Verify the specific suffix 'BCS8' indicates the 0°C to 70°C industrial temperature grade and ±0.05% accuracy class. Confirm the '#PBF' designation aligns with lead-free RoHS compliance requirements. Ensure the ordering part number matches the exact voltage and package specifications required for the design.

Voltage Reference Selection Notes

Select this component when lowest power consumption and guaranteed temperature drift are critical requirements. It serves as a high-performance upgrade to older references like the LM185/LM385 or LT1634 where minimal quiescent current is necessary. Verify that the circuit layout accounts for board leakage currents due to the nanopower nature of the device.

Voltage Reference Part Context

This component belongs to the LT1389 family of nanopower precision shunt voltage references. The family offers various fixed output voltages including 2.5V, 4.096V, and 5V in the same SO-8 package format. The LT1389 series is designed to replace legacy references while providing superior performance in terms of power efficiency and long-term stability.
