INA125P Description

The INA125P from Texas Instruments is a high-precision instrumentation amplifier designed for applications requiring accurate signal conditioning with minimal power consumption. Packaged in a 16-pin DIP (Through Hole), this IC integrates a single-channel instrumentation amplifier with a 2.7V to 36V wide supply voltage range, making it suitable for both low-voltage and industrial-level designs. Its low input bias current (10 nA) and 50 µV input offset voltage ensure high accuracy in sensitive measurements, while the 150 kHz bandwidth and 0.2V/µs slew rate provide adequate speed for most DC and low-frequency AC signal processing tasks.

INA125P Features

• Low Power Consumption: Operates at 460µA supply current, ideal for battery-powered systems.
• Wide Supply Range: Supports 2.7V to 36V, enabling use in diverse voltage environments.
• High Precision: Features 10 nA input bias current and 50 µV offset voltage for accurate signal amplification.
• Robust Output: Capable of driving 12 mA output current, suitable for interfacing with ADCs or other loads.
• Environmental Compliance: ROHS3 Compliant and REACH Unaffected, meeting modern regulatory standards.
• Stable Performance: Not MSL-rated (Moisture Sensitivity Level), ensuring reliability in non-humidity-controlled environments.

INA125P Applications

The INA125P excels in precision measurement systems, including:

• Industrial Sensor Interfaces: Ideal for strain gauges, pressure sensors, and thermocouples due to its low noise and high CMRR.
• Medical Instrumentation: Suitable for ECG amplifiers and biomedical signal conditioning.
• Portable Data Loggers: Its low power consumption makes it perfect for field-deployable equipment.
• Automotive Sensing: Robust performance under wide voltage ranges supports automotive sensor networks.

Conclusion of INA125P

The INA125P stands out as a versatile, high-precision instrumentation amplifier with low power consumption, wide voltage support, and excellent signal integrity. While it is in Last Time Buy status, its performance makes it a reliable choice for legacy or long-lifecycle designs requiring stable amplification in harsh or power-constrained environments. Engineers working on industrial, medical, or portable instrumentation will find it particularly valuable for its balance of accuracy and efficiency.
