LT1019ACS8-5#TRPBF

Voltage Reference Overview

The LT1019ACS8-5#TRPBF is a precision shunt voltage reference manufactured by Analog Devices Inc., featuring a fixed 5V output. It operates within an industrial temperature range of -40°C to +85°C and utilizes an 8-SOIC surface-mount package. Key electrical specifications include an initial accuracy of ±0.2%, a temperature coefficient of 20ppm/°C, and a maximum input voltage of 40V. The device draws a supply current of up to 1.5mA with a minimum cathode current requirement of 800µA for regulation.

Voltage Reference Feature Summary

• Provides stable precision voltage referencing through a shunt architecture
• Ensures high accuracy with low temperature drift characteristics
• Supports wide input voltage ranges for flexible circuit integration

Voltage Reference Applications

• High-resolution analog-to-digital converter (ADC) references
• Precision data acquisition systems
• Calibration equipment requiring stable voltage sources

Voltage Reference Procurement Notes

Verify the specific suffix 'TRPBF' confirms tape-and-reel packaging and lead-free compliance. Confirm the 'A' grade designation matches required accuracy specifications against standard grades. Ensure the SOIC-8 footprint aligns with PCB layout constraints. Validate that the operating temperature range meets environmental requirements.

Voltage Reference Selection Notes

Select this component when a fixed 5V precision reference is required in a compact surface-mount format. Consider the 20ppm/°C temperature coefficient for thermal stability needs. Evaluate the 800µA minimum load current to ensure proper biasing in the target application circuit without excessive power consumption.
