● Bipolar input type: excellent low noise performance with low signal source impedance.

● FET input type: stable low noise performance, signal source impedance independent.

Customized Product

■ Number of channels can be adjusted based on usage.

■ Input Impedance: input impedance can be adjusted based on output impedance of the sensor.

■ Single-Ended Input: When lower noise characteristic are required, a single-ended input can be used.

Equivalent input voltage noise density 0.8 nV/√Hz (bipolar input), 1.6 nV/√Hz (FET input)

■ Downsizing with high-density packaging is available based on your desired features.

We propose the whole measurement system not only with a multi-channel amplifier, but with a post-amplifier and/or AD converter and much more as well.
