DEMO MANUAL DC2487A LTC6363 Rail-to-Rail SAR ADC Driver Amplifier DESCRIPTION Demonstration circuit 2487A features the LTC(R)6363 amplifier. The DC2487A is designed to drive the inputs of the DC2290A demo board. The DC2290A features the LTC(R)2387 18-bit, 15Msps high speed SAR ADC. The linearity and low noise of the LTC6363 make it an ideal candidate to drive -5V the LTC2387 at frequencies up to 100kHz. See Table 1.
