1. Resistant to noise!

< Frequently asked noise-related concerns >

High-precision measurements are required, but it's difficult to avoid the effects of common-mode signal noise!

This product is designed for stable operation even in harsh, noisy measurement environments, achieving a high common-mode rejection ratio (110 dB or more, typically 130 dB at G=100) and excellent EMC performance. Its low input offset voltage (125 µV max.) and low offset voltage drift (1 µV/°C max. *3) enable high-precision measurements. Its wide power supply voltage range of ±2.3 V to ±18 V allows for flexible integration into a variety of equipment. The gain can be set from 1x to a maximum of 10,000x with a single external resistor, simplifying design and contributing to higher accuracy and reduced development time for customers' products.
In addition, we have a domestic development and support system in place, so we can provide prompt and thorough technical support after installation, allowing you to use the product with peace of mind.

1. High common-mode rejection ratio (CMRR) achievedthrough high matching accuracy

This product employs high-precision trimming technology to achieve a high common-mode rejection ratio of 130 dB typ (110 dB min.) @G=100.
The graph below (Figure 1) shows a comparison with representative products from other companies. Fluctuations in the output voltage of the instrumentation amplifier can be minimized in response to large fluctuations in the common-mode input voltage, demonstrating high CMRR performance. This enables stable operation even in environments with a lot of common-mode signal noise, contributing to the high precision of our customers' products.

2. Achieves high EMC performance (see Figures 2 and 3) 
The high EMC performance of this product reduces the risk of rework and contributes to stable application operation, allowing it to be used safely in harsh environments such as industrial equipment sensors and factories.

Even customers who have not had any particular problems with noise until now will now be demanding noise-resistant measures as various sensors become more highly resolved.
In response to this, why not change to a Japanese-made instrumentation amplifier with high CMRR characteristics?

2. Reduction of design man-hours/costs

"Cost reduction" when selecting parts. Are you only comparing the "unit price of parts"?

From now on, why not start thinking in terms of "system costs"?

┗ "The cost of peripheral components such as resistors and capacitors added for EMI countermeasures"

┗ "The number of engineer man-hours required to design and evaluate the filter circuit"

┗ "The cost of the board area itself increases as the number of components increases."

The true cost of a product is determined by the accumulation of these "costs not visible in estimates."​

NISD's domestically produced high-precision instrumentation amplifier "NL9620" was developed with this "TCO (total cost of ownership)" perspective in mind.

■ Major feature

(Former) By incorporating the "EMI filter implemented in the instrumentation amplifier" that New Japan Radio has cultivated in its operational amplifier products,

External filter circuits (resistors, capacitors, etc.) that were previously added as EMI countermeasures are no longer necessary.

<TCO reduction effect achieved by "NL9620">

① Reduction of peripheral component costs (BOM cost reduction)

② Reduction of design and evaluation man-hours (speeding up development)

3) Reduction of board area (product miniaturization and cost reduction)

You may be thinking, "Aren't domestically produced parts expensive?"
"When making a quote, don't compare 'part price vs part price';
Let us compare the costoftheentiresystem, excluding the cost of peripheral components (resistors, capacitors, etc.) thatare no longer needed with the NL9620, implementation costs, and eventhe reduced board costs!
