ADS8860(16-Bit, 1-MSPS, Serial Interface, microPower, Miniature,Single-Ended Input, SAR Analog-to-Digital Converter)IntroductionThe ADS8860 is a 16-bit, 1-MSPS, single-ended input, analog-to-digital converter (ADC). The device operates with a 2.5V to 5V external reference,offering a wide selection of signal ranges without additional input signal scaling. The reference voltage setting is independent of, and Can exceed, the analog supply voltage (AVDD).The device offers an SPI-compatible serial interface that also supports daisy-chain operation for cascading multiple devices.An optional busy-indicator bit makes synchronizing with the digital host easy.The device supports unipolar single-ended analog inputs in the range of -0.1 V to VREF 0.1 V.Device operation is optimized for very low-power operation. Power consumption directly scales with speed. This feature makes the ADS8860 excellent for lower-speed applications.FeatureSample Rate: 1 MHzNo Latency OutputUnipolar, Single-Ended Input Range:0 to VREFSPI™- Compatible Serial Interface withDaisy-Chain OptionExcellent AC and DC Performance: – SNR: 93 dB, THD: -108 dB – INL: 11.0 LSB (typ), ±2.0 LSB (max) – DNL: 1.0 LSB (max), 16-Bit NMCWide Operating Range: – AVDD:2.7Vto3.6V – DVDD: 2.7 V to 3.6 V(Independent of AVDD) – REF: 2.5 V to 5 V (Independent of AVDD) – Operating Temperature: – 40°C to 85°C .Low Power Dissipation: – 5.5mW at 1MSPS – 0.55 mW at 100 kSPS – 55 μW at 10 kSPSPower-Down Current (AVDD): 50 nAFull-Scale Step Settling to 16 Bits: 290 nsPackages: MSOP-10 and SON-10Appearance
