DESCRIPTION
LTC6363
Rail-to-Rail SAR ADC
Driver Amplifier
Demonstration circuit 2487A features the LT C
®
6363 ampli-
fier. The DC2487A is designed to drive the inputs of the
DC2290A demo board. The DC2290A features the LT C
®
2387
18-bit, 15Msps high speed SAR ADC. The linearity and low
noise of the LTC6363 make it an ideal candidate to drive L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear
