Overview
The INA143U/2K5 is a precision differential amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It features a single circuit configuration with a supply voltage range of 4.5 V to 36 V and operates within a temperature range of -40°C to 85°C. Key electrical specifications include a maximum input offset voltage of 100 µV, a slew rate of 5 V/µs, and a -3 dB bandwidth of 150 kHz. The device draws a supply current of 950 µA and provides an output current capability of 32 mA per channel.
Feature Summary
- Provides high-precision differential amplification with low input offset voltage for accurate signal processing.
- Supports wide dual or single power supply operation up to 36 V for flexible system integration.
- Features a compact 8-SOIC surface-mount package suitable for space-constrained designs.
Applications
- Industrial process control systems requiring precise signal conditioning
- Medical instrumentation needing high common-mode rejection
- Data acquisition systems utilizing differential inputs
Procurement Notes
Verify the specific suffix /2K5 indicates tape-and-reel packaging containing 2500 units, distinct from tube packaging. Confirm component status as End-of-Life (EOL) due to Product Change Notification dated September 7, 2023. Ensure RoHS3 compliance and MSL level 3 handling requirements are met during procurement and assembly planning.
Selection Notes
Select this component when a precision differential amplifier with low offset voltage and wide supply range is required. Compare against the standard INA143UA if bulk reel quantities are needed. Consider the EOL status and verify that the 150 kHz bandwidth and 5 V/µs slew rate meet the dynamic performance requirements of the target application circuit.
Part Context
The INA143U/2K5 belongs to the INA143 family of precision differential amplifiers from Texas Instruments. It shares core architectural similarities with other devices in the series but is distinguished by its specific packaging format and quantity. The part is designed to replace legacy components in industrial and medical applications where high accuracy and wide supply voltage tolerance are critical.
Replacement Considerations
INA143UA/2K5 is listed as a manufacturer recommended alternative. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that the base part number INA143 has been subject to end-of-life notifications, making direct replacements necessary for new designs.
