DC2403A - Demo Manual

DEMO MANUAL DC2403A
LT6200
Rail-to-Rail SAR ADC
Driver Amplifier
DESCRIPTION
Demonstration circuit 2403A features the LT®6200 amplifier. The DC2403A includes two of these amplifiers and is
designed to drive the inputs of the DC2290A demo board.
The DC2290A features the LTC®2387 18-bit, 15Msps
high speed SAR ADC. The linearity and low noise of the
LT6200 make it an ideal candidate to drive the LTC2387
at frequencies up to 1MHz. See Table 1.
