- 16 Differential Input Channels via BNC Connectors
- Unity Gain Combines with A/D Gains to Provide Full Scale Inputs from ±156 mV to ±10 V
- Ultra Low-Noise, High-Speed Design
The OMB-DBK85 provides16 channels of differentialvoltage input. It has a single,unity-gain input stage on allchannels. When this is coupledwith the A/D’s on-board x1 throughx64 programmable input gains, fullscale input ranges from ±10 V downto ±156 mV.The OMB-DBK85’s ultra low noise,high-speed design allows users toexpand their input to 256 channelswithout sacrificing measurementintegrity.
