INA110KU

Overview

The INA110KU is a precision instrumentation amplifier from Texas Instruments featuring fast-settling FET inputs. It offers high accuracy with a 3dB bandwidth of 2.5 MHz and a slew rate of 12 V/us. Key electrical parameters include a common-mode rejection ratio (CMRR) of 106 dB, input bias current of 50 pA, and input offset voltage of 250 uV. It operates on a power supply range of 12 V to 36 V with a typical operating current of 3 mA. The device is housed in an SMD/SMT package and supports an operating temperature range from -55 C to +125 C.

Feature Summary

• Fast-settling FET input stage for rapid signal stabilization
• Very high accuracy performance suitable for precision applications
• High common-mode rejection ratio ensuring effective noise suppression

Applications

• Precision data acquisition systems
• Medical equipment requiring high accuracy signal conditioning
• Industrial process control instrumentation

Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure power supply voltages remain within the specified 12 V to 36 V limits to maintain performance and reliability.

Selection Notes

Select this component when high-speed settling and low input bias current are critical. The 2.5 MHz bandwidth supports applications requiring faster response times compared to lower-bandwidth alternatives. Consider the SMD package style for automated assembly processes and space-constrained designs.

Part Context

The INA110KU belongs to the INA110 series of instrumentation amplifiers manufactured by Texas Instruments. This series is designed for applications demanding high precision and speed. The KU suffix typically denotes a specific package variant within the family, distinguishing it from through-hole options like the SG suffix.

Replacement Considerations

Check for direct pin-compatible substitutes within the INA110 family or other TI instrumentation amplifiers with similar bandwidth and accuracy specifications. Verify that any replacement maintains the required FET input characteristics and operating temperature range.
