DEMO MANUAL DC2403A LT6200 Rail-to-Rail SAR ADC Driver Amplifier DESCRIPTION Demonstration circuit 2403A features the LT 6200 ampli- LT6200 make it an ideal candidate to drive the LTC2387 fier. The DC2403A includes two of these amplifiers and is at frequencies up to 1MHz. See Table 1. designed to drive the inputs of the DC2290A demo board. Design files for this circuit board are available at The DC2290A features the LTC 2387 18-bit, 15Msps DEMO MANUAL DC2403A QUICK START PROCEDURE Connect the DC2403A to a DC2290A using the two output SMA connectors J2, J4. Connect the +10V and 5V DC supplies to the turrets on the DC2403A. HARDWARE SETUP SIGNAL CONNECTIONS J1 +IN. This is the positive signal input. J3 IN. This is the negative signal input. J4 OUT. This is the negative signal output. J2 +OUT. This is the positive signal output.
