1 / 42 page GND REF ADS8866 AINP AINM AVDD DIN SCLK DOUT CONVST 0 V - VREF 2.5 V to 5 V DVDD Digital Host 2.7 V to 3.6 V No separate LDO Required for ADC supply ADS8866 www.ti.com SBAS614A – MAY 2013 – REVISED DECEMBER 2013 16-Bit, 100-kSPS, Serial Interface, microPower, Miniature, Single-Ended Input, SAR Analog-to-Digital Converter Check for Samples: ADS8866 1 FEATURES APPLICATIONS 234 • Sample Rate: 100 kHz • Automatic Test Equipment (ATE) • No Latency Output • Instrumentation and Process Controls • Unipolar, Single-Ended Input Range: • Precision Medical Equipment 0 to +VREF • Low-Power, Battery-Operated Instruments • SPI™-Compatible Serial Interface with Daisy-Chain Option DESCRIPTION The ADS8866 is a 16-bit, 100-kSPS, single-ended • Excellent AC and DC Performance: input, analog-to-digital converter (ADC). The device – SNR: 93 dB, THD: –108 dB operates with a 2.5-V to 5-V external reference, – INL: ±1.0 LSB (typ), ±2.0 LSB (max) offering a wide selection of signal ranges without additional input signal scaling. The reference voltage – DNL: ±1.0 LSB (max), 16-Bit NMC setting is independent of, and can exceed, the analog • Wide Operating Range: supply voltage (AVDD). – AVDD: 2.7 V to 3.6 V The device offers an SPI-compatible serial interface – DVDD: 1.65 V to 3.6 V that also supports daisy-chain operation for (Independent of AVDD) cascading multiple devices. – REF: 2.5 V to 5 V (Independent of AVDD) The device supports unipolar single-ended analog – Operating Temperature: –40°C to +85°C inputs in the range of –0.1 V to VREF + 0.1 V. • Low-Power Dissipation: Device operation is optimized for very low-power – 0.7 mW at 100 kSPS operation. Power consumption directly scales with – 70 µW at 10 kSPS speed. This feature makes the ADS8866 excellent for lower-speed applications. • Power-Down Current (AVDD): 50 nA • Full-Scale Step Settling to 16 Bits: 1200 ns • Packages: MSOP-10 and SON-10 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 TINA is a trademark of Texas Instruments Inc.. 3 SPI is a trademark of Motorola Inc. 4 All other trademarks are the property of their respective owners.
