These channels are grouped in – ADS8528: 650kSPS (PAR) or four pairs, thus allowing simultaneous high-speed signal acquisition of up to 650kSPS. 480kSPS (SER) – ADS8548: 600kSPS (PAR) or The devices support selectable parallel or serial 450kSPS (SER) interface with daisy-chain capability. The programmable reference allows handling of analog – ADS8568: 510kSPS (PAR) or input signals with amplitudes up to ±12V. 400kSPS (SER) The ADS8528/48/68 family supports an auto-sleep • Excellent AC Performance: mode for minimum power dissipation and is available – Signal-to-Noise Ratio: in both QFN-64 and LQFP-64 packages. The entire ADS8528: 73.9dB family is specified over a temperature range of –40°C ADS8548: 85dB to +125 °C. ADS8568: 91.5dB – Total Harmonic Distortion: ADS8528: –89dB ADS8548: –91dB ADS8568: –94dB • Programmable and Buffered Internal Reference: 0.5V to 2.5V or 0.5V to 3.0V Supports Input Voltage Ranges of Up to ±12V • Selectable Parallel or Serial Interface • Scalable Low-Power Operation Using Auto-Sleep Mode: Only 32mW at 10kSPS • Fully Specified Over the Extended Industrial Temperature Range APPLICATIONS • Protection Relays • Power Quality Measurement • Multi-Axis Motor Control • Programmable Logic Controllers • Industrial Data Acquisition 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 All trademarks are the property of their respective owners.
