DEMO MANUAL DC2403A
DESCRIPTION
LT6200
Rail-to-Rail SAR ADC
Driver Amplifier
Demonstration circuit 2403A features the
LT
®
6200
ampli-
fier. 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
