ADC128S102SNAS298G –AUGUST 2005–REVISED JANUARY 2015
ADC128S102 8-Channel, 500-kspsto 1-Msps, 12-Bit A/D Converter Features 3 DescriptionThe ADC128S102 isa low-power, eight-channel Eight Input Channels CMOS 12-bit analog-to-digital converter specified for• Variable Power Management conversion throughput ratesof 500 kspsto1 MSPS.• Independent Analog and Digital Supplies The converter is based on a successive-
approximation register architecture with an internal• SPI/QSPI™/MICROWIRE™/DSP Compatible track-and-hold circuit.It can be configuredto accept• Packagedin 16-Lead TSSOP upto eight input signalsat inputs IN0 through IN7.• Key Specifications The output serial data is straight binary and is– Conversion Rate 500 kspsto1 MSPS compatible with several standards, such as SPI,– DNL (VA= VD= 5.0V) +1.5/ −0.9 QSPI, MICROWIRE, and many common DSP serial
interfaces.– LSB (maximum) INL (VA= VD= 5.0V) ±1.2
LSB (maximum) The ADC128S102 maybe operated with independent Power Consumption analog and digital supplies. The analog supply (VA)
can range from +2.7Vto +5.25 V, and the digital– 3V Supply 2.3 mW (typical) supply (VD) can range from +2.7Vto VA. Normal– 5V Supply 10.7 mW (typical) power consumption usinga +3-Vor +5-V supplyis
2.3 mW and 10.7 mW, respectively. The power-down
2 Applications feature reduces the power consumptionto 0.06 µW
