and Connectors section of this manual. The default con-

nections configure the ADC to use the onboard reference

and regulators to generate all the required bias voltages.

The analog inputs by default are DC coupled. Connect the

DC2412A to a DC890 USB High Speed Data Collection

Board using connector P1. Then, connect the DC890 to

a host PC with a standard USB A/B cable. Apply ±16V

to the indicated terminals. Then apply a low jitter signal

source to J5 and J6. Use J7 to route the signal sources

of J5 and J6 to the desired IN0 to IN7 inputs. Observe the

recommended input voltage range for each analog input.

connector J1. See DC2412 Assembly Options table for

the appropriate clock frequency. Note that J1 has a 50Ω

termination resistor to ground.
