Overview
The INA141UA/2K5 is a precision instrumentation amplifier from Texas Instruments, featuring fixed gains of 10 V/V and 100 V/V selectable via external resistors. It operates on a single supply voltage ranging from 3V to 36V or dual supplies of ±1.5V to ±18V. The device offers low power consumption with a typical supply current of 700µA per channel. It provides high common-mode rejection ratio (CMRR) and low input bias current, making it suitable for battery-powered applications. The component is housed in an 8-pin SOIC package.
Feature Summary
- Fixed gain configuration options of 10 V/V and 100 V/V
- Low power operation with minimal supply current requirements
- High common-mode rejection ratio for accurate signal conditioning
- Single-supply compatibility for simplified system design
Applications
- Battery-powered sensor interfaces
- Industrial process control systems
- Medical instrumentation equipment
- Data acquisition systems
Procurement Notes
Verify the specific suffix '2K5' indicates reel packaging when ordering. Confirm the required gain setting matches the application needs as the internal architecture supports fixed gain selections. Ensure the operating environment stays within the specified temperature range for optimal performance. Check for RoHS compliance status if environmental regulations apply to the final product assembly.
Selection Notes
Select this component when a fixed gain instrumentation amplifier is preferred over adjustable gain configurations to reduce external component count. Consider the INA141 for applications requiring high CMRR at lower power levels compared to general-purpose op-amps. Evaluate the input voltage range against the expected signal amplitude to ensure linear operation without saturation.
Part Context
The INA141 belongs to the family of precision instrumentation amplifiers designed by Texas Instruments. It integrates multiple matched components on a single die to achieve high accuracy and stability. The UA/2K5 variant specifies the surface-mount package type and tape-and-reel quantity for automated assembly processes.
Replacement Considerations
INA141P: Pin-compatible alternative in DIP package. INA128: Adjustable gain instrumentation amplifier with similar power specs. INA129: Higher bandwidth option within the same family.
