LT1004IPWR-1-2

Voltage Reference Overview

The LT1004IPWR-1-2 is a micropower integrated precision voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.2 V with an initial accuracy of 0.8%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 20 mA. It utilizes a TSSOP-8 surface-mount package and exhibits a temperature coefficient of 20 ppm/°C, ensuring stable performance across varying thermal conditions.

Voltage Reference Feature Summary

• Provides a fixed 1.2 V precision output for stable reference applications
• Operates as a shunt reference with micropower consumption characteristics
• Maintains specified accuracy over the industrial temperature range

Voltage Reference Applications

• Analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Precision measurement instrumentation circuits

Voltage Reference Procurement Notes

Verify the specific suffix IPWR indicates the TSSOP-8 tape-and-reel packaging configuration. Confirm the -1-2 designation corresponds to the 1.2 V output variant. Ensure compatibility with the required operating temperature range of -40°C to +85°C for your application environment before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a low-cost, micropower shunt reference is required for 1.2 V applications. Consider the 0.8% initial accuracy and 20 ppm/°C temperature coefficient against stricter precision requirements. Evaluate the TSSOP-8 package size constraints relative to available board space.

Voltage Reference Part Context

This part belongs to the LT1004 series of micropower integrated voltage references from Texas Instruments. The series offers various fixed output voltages including 1.2 V, 2.5 V, and 12 V options. These devices are designed to replace zener diodes in precision applications requiring better stability and lower power consumption.

Voltage Reference Replacement Considerations

LT1004IPWR-2-5: Provides 2.5 V output instead of 1.2 V. LM285-2.5: Different output voltage and package options. Verify pinout and electrical specifications match before substitution.
