Overview
The INA2126UA/2K5 is a dual micropower instrumentation amplifier manufactured by Texas Instruments. It features two independent channels in a 16-SOIC package. Key electrical specifications include a gain bandwidth product of 200 kHz, a common mode rejection ratio of 83 dB, and an input bias current of 10 nA. The device operates on a supply voltage range from 2.7 V to 36 V with a typical operating supply current of 175 µA per channel. Input offset voltage is specified at 150 µV, and the slew rate is 0.4 V/µs.
Feature Summary
- Dual-channel micropower instrumentation amplifier architecture
- High common mode rejection ratio for precision signal conditioning
- Wide single-supply voltage operation capability
Applications
- Battery-powered sensor interfaces
- Medical instrumentation front-ends
- Industrial process control systems
Procurement Notes
Verify the specific suffix '2K5' indicates tape-and-reel packaging containing 2500 units. Confirm the SOIC-16 package dimensions match design constraints. Check RoHS compliance status as indicated in official documentation. Ensure moisture sensitivity level requirements are met for assembly processes. Validate that the 10 nA input bias current meets system leakage requirements.
Selection Notes
Select this component when dual-channel precision amplification is required with low power consumption. The 2.7 V minimum supply voltage supports battery-operated applications. Compare input offset voltage and bias current against other INA126 variants if higher precision is needed. Consider the 200 kHz bandwidth for frequency response limitations in high-speed applications.
Part Context
This part belongs to the INA2126 family of micropower instrumentation amplifiers. It offers dual-channel functionality compared to single-channel counterparts like the INA2126A. The UA variant denotes the SOIC surface-mount package. The 2K5 suffix specifies reel packaging for automated assembly. This series is designed for general-purpose precision analog signal processing tasks.
Replacement Considerations
INA2126EA-2K5: Equivalent dual-channel instrumentation amplifier in SSOP-16 package. INA2126PA: Dual-channel version in PDIP through-hole package. INA2126E/250: Dual-channel instrumentation amplifier in SSOP-16 tube packaging.
