16-bit, 500-kSPS, eight-channel, single-supply SAR ADC with ±12-V differential inputs The ADS8684W and ADS8688W are 4-channel and 8-channel, integrated data acquisition systems based on a 16-bit successive approximation (SAR) analogto-digital converter (ADC), operating at a throughput of 500kSPS. The devices feature integrated analog front-end circuitry for each input channel with overvoltage protection up to ±20V, a 4-channel or 8-channel multiplexer with automatic and manual scanning modes, and an on-chip, 4.096V reference with low temperature drift. Operating on a single 5V analog supply, each input channel on the devices can independently support bipolar input ranges of ±12.288V, ±6.144V, and ±3.072V and unipolar input ranges of 12.288V to 0V and 6.144V to 0V. The ADS8684W and ADS8688W offer a simple SPIcompatible serial interface to the digital host and also support daisy-chaining of multiple devices. The digital supply operates from 1.65V to 5.25V, enabling direct interface to a wide range of host controllers Features • 16-Bit ADCs with Integrated Analog Front-End • 4-, 8-Channel MUX with Auto and Manual Scan • Channel-Independent Programmable Inputs: – ±12.288V, ±6.144V, and ±3.072V – 12.288V to 0V and 6.144V to 0V • 5V Analog Supply: 1.65V to 5V I/O Supply • Constant Resistive Input Impedance: 1.2MΩ • Input Overvoltage Protection: Up to ±20V • On-Chip, 4.096V Reference with Low Drift • Excellent Performance: – 500kSPS Aggregate Throughput – DNL: ±0.6LSB; INL: ±0.8LSB – Low Drift for Gain Error and Offset – SNR: 91.5dB; THD: –102dB – Low Power: 65mW • AUX Input → Direct Connection to ADC Inputs • ALARM → High and Low Thresholds per Channel • SPI™-Compatible Interface with Daisy-Chain • Industrial Temperature Range: –40°C to 125°C #commonpartslibrary #ADS8688W #TexasInstruments #ADC #SARADC #DataAcquisition #IndustrialAutomation #SPI #PrecisionADC #AnalogFrontEnd #EmbeddedSystems #MeasurementSystems
