Overview
The INA2126PAG4 is a dual micropower instrumentation amplifier from Texas Instruments, housed in a 16-pin TSSOP package. It operates on a single supply of 2.7 V to 36 V or dual supplies of ±1.35 V to ±18 V. Key electrical parameters include a gain bandwidth product of 200 kHz, a maximum input offset voltage of 250 µV, and a minimum common-mode rejection ratio of 83 dB. The device draws a typical supply current of 175 µA per amplifier and features a slew rate of 0.4 V/µs.
Feature Summary
- Micropower consumption with low operating supply current suitable for battery-powered applications
- High precision performance characterized by low input offset voltage and high common-mode rejection ratio
- Wide single-supply or split-supply voltage operation range for flexible system integration
Applications
- Portable medical instrumentation requiring low power and high accuracy
- Industrial process control sensor signal conditioning
- Data acquisition systems utilizing low-voltage microcontrollers
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type corresponds to the TSSOP-16 variant rather than other available packages like PDIP or SOIC. Ensure the order quantity matches the standard tube packaging format typically associated with this part number designation.
Selection Notes
Select this component when a dual-channel instrumentation amplifier is required with strict power constraints. It is appropriate for designs needing a wide common-mode voltage range without rail-to-rail output limitations. Consider the 200 kHz bandwidth and 0.4 V/µs slew rate against the signal frequency requirements of the application.
Part Context
This part belongs to the INA2126 family of micropower instrumentation amplifiers, which also includes single-channel versions and variants with different offset voltage grades. The G4 suffix denotes environmental compliance. The device serves as a general-purpose solution for precision analog signal processing in compact electronic systems.
Replacement Considerations
Direct pin-compatible alternatives within the same family include the INA2126PA and INA2126E series. Verify that substitute parts match the required offset voltage grade and package dimensions before implementation.
