Description

The OMB-DBK85 provides 16 channels of differential voltage input. It has a single, unity-gain input stage on all channels. When this is coupled with the A/D’s on-board x1 through x64 programmable input gains, full scale input ranges from ±10 V down to ±156 mV. The OMB-DBK85’s ultra low noise, high-speed design allows users to expand their input to 256 channels without sacrificing measurement integrity.
