The TLC5510 and DGND 2 23 REFB TLC5510A operate with a single 5-V supply and D1(LSB) 3 22 REFBS typically consume only 130 mW of power. D2 4 21 AGND Included is an internal sample-and-hold circuit, D3 5 20 AGND parallel outputs with high-impedance mode, and D4 6 19 ANALOG IN internal reference resistors. D5 7 18 VDDA The semiflash architecture reduces power consumption and die size compared to flash converters. By implementing the conversion in a 2-step process, the number of comparators is significantly reduced. The latency of the...
