Voltage Reference datasheet and documents for LT1009CD

LT1009CD

Voltage Reference Overview

The LT1009CD is a precision shunt voltage reference manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 25 PPM/°C. Electrical specifications include a maximum shunt current of 10 mA and a minimum operating current of 400 µA.

Voltage Reference Feature Summary

Integrated on-chip trimming minimizes initial voltage tolerance and temperature coefficient for high precision.
Features an adjustable terminal allowing reference voltage modification by ±5% to compensate for system errors.
Designed as a low dynamic impedance parallel regulator suitable for direct replacement without external trim networks.

Voltage Reference Applications

Providing stable reference voltages for 8-bit analog-to-digital converters (ADCs).
Serving as reference sources for digital-to-analog converters (DACs).
Power supply monitoring circuits requiring precise threshold detection.

Voltage Reference Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure the ordering part number matches the required SOIC-8 configuration and industrial temperature range specifications before procurement.

Voltage Reference Selection Notes

Select this component when a compact surface-mount solution is required for precision analog applications. The integrated adjustability feature allows for system-level error correction, reducing the need for external components compared to standard fixed references.

Voltage Reference Part Context

This device belongs to the LT1009 series of precision shunt references. The family includes variants such as LT1009CLP and LT1009IPWR, which share similar electrical characteristics but differ in packaging options like TO-92 or TSSOP-8 to accommodate different board layout requirements.
