Overview
The INA2321EA/2K5 is a dual-channel, micropower instrumentation amplifier from Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical operating current of 40 uA. Key electrical specifications include a 500 kHz bandwidth, 90 dB common-mode rejection ratio (CMRR), and an input bias current of 10 pA. The device features a gain range of 5 V/V to 1000 V/V with a maximum gain error of 0.01%. It is housed in a 14-TSSOP package and supports an operating temperature range from -55°C to +125°C.
Feature Summary
- Dual-channel architecture for simultaneous signal processing
- Micropower CMOS design optimized for low energy consumption
- High precision performance with low offset voltage and bias current
Applications
- Battery-powered sensor interfaces
- Industrial process control systems
- Medical instrumentation devices
Procurement Notes
Verify the specific suffix /2K5 indicates the reel packaging quantity of 2500 units when ordering. Confirm that the TSSOP-14 package dimensions match your PCB footprint requirements. Ensure the 2.7 V to 5.5 V supply range aligns with your system power rails. Check RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when dual-channel amplification is required within a micropower constraint. The 10 pA input bias current makes it suitable for high-impedance sources. The wide gain range allows flexibility in signal conditioning without external resistors. Consider the 14-TSSOP package size for space-constrained designs.
Part Context
This part belongs to the INA2321 series of micropower instrumentation amplifiers. It shares core specifications with variants like INA2321EA/250 but differs in packaging configuration. The series is designed for applications requiring low power and high accuracy in single-supply environments.
Replacement Considerations
INA2321EA/250 offers identical electrical characteristics but in a tape-and-reel format of 250 units. Verify pin compatibility and thermal performance before substitution.
