Overview
The INA156EA/2K5 is a single-channel instrumentation amplifier from Texas Instruments, housed in an 8-pin VSSOP package. It operates on a single supply voltage ranging from 2.7V to 36V. The device features rail-to-rail output swing and offers a fixed gain of 10 V/V. Key electrical specifications include a maximum input offset voltage of 1mV, a common-mode rejection ratio (CMRR) of 90dB at a gain of 10, and a bandwidth of 400kHz. It draws a typical supply current of 1.2mA per channel.
Feature Summary
- Rail-to-rail output capability optimized for low-voltage single-supply operation
- Fixed internal gain of 10 V/V eliminates external resistor requirements
- High common-mode rejection ratio ensures accurate signal processing
- CMOS technology provides low power consumption
Applications
- Battery-powered sensor interfaces
- Industrial process control systems
- Medical instrumentation
Procurement Notes
Verify the suffix '2K5' indicates tape-and-reel packaging with a quantity of 2,500 units. Confirm the base part number INA156 matches the required fixed gain of 10 V/V. Ensure the VSSOP-8 package is compatible with your PCB footprint. Check RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a fixed gain of 10 is sufficient for the application. It is suitable for single-supply environments requiring rail-to-rail output. Consider alternatives if variable gain or higher precision offset voltage is needed. Verify that the 400kHz bandwidth meets the signal frequency requirements.
Part Context
This part belongs to the INA15x family of low-cost CMOS instrumentation amplifiers. The series is designed for applications requiring high accuracy in single-supply systems. The EA suffix denotes the VSSOP-8 package variant. The /2K5 suffix specifies the reel packaging configuration.
Replacement Considerations
INA156E: Same functional specifications but in a different package type. INA156EA/250: Identical electrical performance but packaged in a 250-unit reel instead of 2,500.
