INA110KP

Overview

The INA110KP is a precision instrumentation amplifier from Texas Instruments featuring FET inputs for high accuracy and fast settling. It operates on a single supply voltage ranging from 12 V to 36 V with a typical operating current of 3 mA. Key electrical specifications include a 470 kHz bandwidth, 12 V/µs slew rate, and 106 dB common-mode rejection ratio. Input bias current is limited to 50 pA, while input offset voltage is 250 µV. The device provides gain options of 1, 10, 100, or 1000 V/V with a gain error of 0.01%. It supports output currents up to 25 mA and functions within a temperature range of -55°C to +125°C in a CDIP-16 package.

Procurement Notes

Verify the specific suffix 'KP' against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the required pin configuration and material compliance standards. Cross-reference manufacturer documentation for any recent lifecycle status changes or recommended alternative components before finalizing procurement.

Selection Notes

Select this component when high precision and fast settling are required in a single-supply environment. The FET input stage minimizes bias current errors, making it suitable for high-impedance sources. Evaluate the 12 V minimum supply requirement against system power constraints. Consider the CDIP-16 package for through-hole mounting needs in rugged applications.
