Overview
The REF3312AIDCKTG4 is a fixed series voltage reference IC manufactured by Texas Instruments, delivering a precise output of 1.25 V. It features an initial accuracy of 0.15% and a temperature coefficient of 30 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 5 mA. It consumes only 3.9 µA of supply current. The component is housed in a compact SC70-3 surface-mount package and functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Provides stable 1.25 V reference with high precision
- Ultra-low power consumption for battery applications
- Compact SC70-3 surface-mount packaging
Applications
- Portable instrumentation systems
- Battery-powered measurement devices
- Data acquisition systems requiring stable references
Procurement Notes
Verify the complete part number including suffixes such as TG4 against official manufacturer documentation to ensure correct package and tape-and-reel specifications. Confirm end-of-life status if long-term availability is required. Check humidity sensitivity levels and storage conditions prior to assembly to prevent moisture-related damage during soldering processes.
Selection Notes
Select this component when a low-cost, low-power voltage reference is needed for single-supply applications. The 1.25 V output suits ADCs and DACs requiring mid-range references. Ensure the load current does not exceed 5 mA. Verify that the SC70-3 footprint matches the PCB layout constraints and thermal requirements of the design.
Part Context
This part belongs to the REF3312 family of precision voltage references from Texas Instruments. The family offers various output voltages and packages. The IDCKT suffix indicates the SC70-3 package with specific reel quantities. It is designed for general-purpose precision applications where size and power are critical constraints.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family, such as other REF331x variants with different output voltages or packages like SOT-23-3. Verify electrical parameters match exactly before substitution.
