Instrumentation Amplifier Texas Instruments INA110KP, single-channel, DIP-16

The Texas Instruments INA110KP is a single-channel instrumentation amplifier supplied in a DIP-16 package. It is designed for accurate differential signal amplification and precise gain control, making it suitable for sensor interfaces and measurement chains. The device targets low-noise front-end circuits, signal conditioning stages and data acquisition systems where stable gain and common-mode rejection are important for converting small differential signals into usable levels.

Advantages

The amplifier provides stable and precise gain with low noise contribution and good common-mode rejection, enabling improved measurement accuracy. Its DIP-16 through-hole package simplifies prototyping, breadboarding and retrofit into existing systems. The device’s single-channel architecture reduces board space compared with multi-channel alternatives when only one input needs conditioning.

Suitable for

• Interfacing bridge sensors and transducers
• Low-noise front-end for data acquisition
• Signal conditioning in laboratory instruments
• Embedded measurement systems and prototyping

Key specifications

• Single instrumentation amplifier channel
• DIP-16 through-hole package for easy prototyping
• Precision differential amplification with adjustable gain
• Low input-referred noise for sensitive measurements
• High common-mode rejection ratio to minimize interference
• Suitable for single- or dual-supply operation depending on circuit design

How to use

Place the INA110KP into a compatible DIP-16 socket or solder it to a PCB footprint designed for through-hole components. Configure the required gain per the manufacturer's recommended external resistor network or circuit configuration, taking care to follow recommended layout practices to minimize noise and maintain common-mode rejection. Provide appropriate supply rails and bypassing capacitors close to the supply pins, and route differential input traces as matched pairs to reduce interference.

Recommendations

For optimal performance, use short, matched routing for differential inputs, place power supply decoupling capacitors near the amplifier, and follow the manufacturer’s guidelines for external gain-setting components. When measuring very small signals, use shielded connections and a low-noise reference to preserve signal integrity.
