DEMO MANUAL DC2402A LT6237: Rail-to-Rail SAR ADC Driver Amplifier Description Demonstration circuit 2402A features the LT 6237 ampli- LT6237 make it an ideal candidate to drive the LTC2387 fier. The DC2402A includes two of these amplifiers and at frequencies up to 8kHz. See Table 1. is designed to drive the inputs of the DC2290A demo Design files for this circuit board are available at board. The DC2290A features the LTC2387 18-bit, 15Msps DEMO MANUAL DC2402A Quick s p D Connect the DC2402A to a DC2290A using the two output SMA connectors J2 and J4. Connect +10V and 5V DC supplies to the turrets on the DC2402A. h D s SIgNAL CONNECTIONS J4 OUT. This is the negative signal output. J1 +IN. This is the positive signal input. J2 +OUT. This is the positive signal output. J3 IN. This is the negative signal input. p List ITEM QTY REFERENCE PART DESCRIPTION MANUFACTURER/PART NUMBER Required Circuit Components 1 1 C4, C6, C14, C16, C21, C23 CAP., TANT, 10F, 16V, 20%, 0805 VISHAY, 298D106X0016R2T 2 2 C3, C5 CAP., X5R, 1F, 16V, 10%, 0603 AVX, 0603YD105KAT2A 3 3 C1, C2 CAP., X5R, 22F, 16V 10%, 1210 AVX, 1210YD226KAT2A 4 4 C7, C9, C10, C12 CAP., X5R, 0.1F, 16V 10% 0402 AVX, 0402YD104KAT2A 5 5 C13 CAP., X7R, 0.01F, 6.3V 10%, 0603 MURATA, GRM188R70J103KA01D 6 2 C20, C21 CAP., X7R, 0.01F, 16V, 10%, 0402 AVX, 0402YC103KAT2A 7 6 C8, C11 CAP., NPO, 1000pF, 50V, 5%, 1206 MURATA, GRM3195C1H102JA01D 8 7 C15, C18 CAP., NPO, 0.027F, 50V, 5%, 1206 MURATA, GRM3195C1H273JA01D 9 8 E5, E4 TEST POINT, TURRET, .064 MILL MAX, 2308-2-00-80-00-00-07-0 10 9 E1, E2, E3 TEST POINT, TURRET, .094 MILL-MAX, 2501-2-00-80-00-00-07-0 11 2 J1, J3 CONN., SMA, 50-OHM, EDGE-LAUNCH, FEMALE E.F.
