Product Overview
The Burr-Brown INA105KP is a monolithic precision unity-gain differential amplifier built on an 8-pin plastic DIP footprint. It combines a premium operational amplifier with an on-chip, laser-trimmed resistor network composed of four matched 25 kΩ resistors. Designed for accurate signal conditioning without requiring external trim components, it provides tight gain accuracy and high common-mode rejection for differential signal chains and instrumentation stages.
Key Features
- Fixed unity gain (Gain = 1)
- On-chip laser-trimmed internal resistor network (four matched 25 kΩ resistors)
- Gain error rated at 0.01% maximum
- Nonlinearity rated at 0.001% maximum
- Minimum common-mode rejection of 86 dB
- Operates across a ±5V to ±18V dual supply range (or single-supply up to 36V)
- Standard through-hole 8-pin DIP package
Applications
- Replacing failed differential input stages in legacy audio mixers and analog test gear
- Building balanced line receivers for custom audio interfaces and modular synthesizers
- Conditioning bridge sensor outputs and current shunt signals on custom maker bench projects
- Maintaining legacy industrial control boards and laboratory instrumentation
Frequently Asked Questions
What package style is this INA105KP?
This unit is housed in a standard through-hole 8-pin plastic dual in-line package (DIP-8).
Are external gain-setting resistors required for unity-gain operation?
No. The INA105KP includes an integrated, laser-trimmed 25 kΩ resistor network on-chip for precision unity-gain differential amplification without external balancing components.
Why purchase this single pulled Burr-Brown IC?
Finding genuine original Burr-Brown analog silicon often means wading through questionable bulk overseas lots. This single pull provides clear top markings confirming genuine manufacture, photographed directly so you know the exact piece in hand. Shipping is an $8 flat rate, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Drop this classic Burr-Brown diff amp into your signal chain and let laser-trimmed precision handle the balancing without the headache of sorting discrete resistors.
