Overview
The INA125TDA1 is a die-level instrumentation amplifier from Texas Instruments, featuring an integrated precision voltage reference. It operates with low quiescent current of 460µA and offers a maximum offset voltage of 250µV. The device supports sleep mode functionality and provides selectable reference outputs of 1.24V, 2.5V, 5V, or 10V. Designed for high accuracy applications, it serves as a complete solution for bridge excitation and signal conditioning in compact surface-mount implementations.
Feature Summary
- Integrates a precision voltage reference for complete bridge excitation
- Features low power consumption with 460µA quiescent current
- Includes sleep mode capability for energy conservation
- Provides high accuracy with low offset voltage specifications
Applications
- Precision bridge sensor signal conditioning
- Low-power instrumentation systems
- Battery-operated measurement devices
- Industrial process control transmitters
Procurement Notes
Verify the specific suffix configuration against the official datasheet to ensure compatibility with required reference voltage options and package constraints. Confirm that the die form factor aligns with your substrate design capabilities. Cross-reference the manufacturer's latest documentation for any updates regarding pin assignments or electrical characteristics before finalizing procurement.
Selection Notes
Select this component when a monolithic solution combining instrumentation amplification and voltage reference generation is required. It is suitable for designs prioritizing low power consumption and high accuracy in small footprints. Ensure the application can accommodate die-level mounting and verify thermal management requirements for the specific operating environment.
Part Context
This part belongs to the INA125 family of instrumentation amplifiers manufactured by Texas Instruments. It represents the die version of the standard packaged INA125, offering the same electrical performance in a bare die format. This allows system integrators to customize packaging and interconnects while maintaining the benefits of integrated reference and low-power operation.
Replacement Considerations
Direct die-to-die replacements are limited. Consider the packaged INA125U or INA125UA if board space permits. Verify functional equivalence with other Burr-Brown derived instrumentation amplifiers only after confirming pinout and electrical parameter alignment through official cross-reference data.
