INA105KU/2K5

Overview

The INA105KU/2K5 is a precision unity-gain differential amplifier manufactured by Texas Instruments. It integrates a single operational amplifier circuit within an 8-SOIC surface-mount package. The device operates on supply voltages ranging from 10 V to 36 V, with a maximum span of 36 V. Key electrical characteristics include a 1 MHz bandwidth, a slew rate of 3V/µs, and an input offset voltage of 50 µV. It draws 1.5 mA of supply current and provides a channel output current of 20 mA. The component functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

Integrated precision differential amplifier architecture
Fixed unity gain configuration for signal conditioning
Low power consumption design suitable for battery applications

Applications

Industrial process control signal isolation
Medical equipment sensor interface circuits
Data acquisition system front-end conditioning
High-voltage differential measurement systems

Procurement Notes

Verify the specific suffix /2K5 indicates reel packaging when ordering. Confirm RoHS3 compliance status for environmental regulations. Ensure the 8-SOIC footprint matches the target PCB layout dimensions. Check moisture sensitivity level requirements for reflow soldering profiles.

Selection Notes

Select this component when a fixed unity-gain differential conversion is required without external resistor networks. Consider the 50 µV offset voltage for high-precision low-level signal applications. Evaluate the 1 MHz bandwidth against the highest frequency components in the input signal spectrum.

Part Context

This part belongs to the INA105 family of precision differential amplifiers. The KU designation specifies the SOIC package variant. The /2K5 suffix denotes the standard tape and reel quantity for automated assembly processes. It serves as a dedicated solution for converting differential signals to single-ended outputs.

Replacement Considerations

Official substitutes include AD629ANZ and AD629ARZ from Analog Devices Inc. Verify pin compatibility and electrical parameter alignment before substitution. Ensure the replacement maintains the required differential input capability.
