In industrial measuring instruments, the use of dedicated sensors is common because more precise monitoring is required. Therefore, even when handling minute differential input signals, the presence of "instrumentation amplifiers" with excellent accuracy and reliability is indispensable.
This product is the first instrumentation amplifier IC to be commercialized in Japan in a field that has previously relied on overseas products. It was developed by combining our proprietary process technology, trimming technology, and packaging technology in addition to the high-precision operational amplifier circuit design technology that we have cultivated over many years, and has succeeded in bringing out the highest level of performance.
Designed for stable operation even in harsh, noisy measurement environments, it achieves a high common-mode rejection ratio (110 dB or more, 130 dB typical @G=100) and excellent EMC performance. It also features low input offset voltage (125 µV max.) and low offset voltage drift (1 µV/°C max. *2) This enables highly accurate measurements.
Furthermore, it supports a wide power supply voltage range of ±2.3V to ±18V, allowing it to be flexibly incorporated into a variety of devices. The gain can be set from 1x to a maximum of 10,000x with a single external resistor, simplifying the design and contributing to higher accuracy of our customers' products and reducing development man-hours.
We also have an in-house development and support system in place, and can provide prompt and thorough technical support after implementation, so you can use our products with peace of mind.

Features
High common-mode rejection ratio (CMRR) achieved through high matching accuracy
This product achieves a high common-mode signal rejection ratio of 130dB typ (110dB min.) @G=100 by adopting high-precision trimming technology. The graph below shows a comparison with representative products from other companies.
The output voltage fluctuation of the instrumentation amplifier can be minimized even when there is a large fluctuation in the common-mode input voltage, and high CMRR performance is demonstrated. This enables stable operation even in environments with a lot of common-mode signal noise, contributing to the high precision of our customers' products.
Achieves high EMC performance
The high EMC performance of this product reduces the risk of rework and contributes to stable operation of applications, allowing you to use it with confidence even in harsh environments such as industrial equipment sensors and factories.
