The design includes a 16-bit capacitor-based SAR A/D converter with an inherent sample and hold (S/H), a precision reference, and an internal clock. Spurious-free dynamic range with a 100kHz full-scale sinewave input is typically greater than 100dB. The ±2.5V input range allows development of precision systems using only ±5V supplies. The converter is available in a 28-lead SOIC package specified for operation over the industrial –25°C to +85°C temperature range. ±2.5V Input REF Out/In Clock Successive Approximation Register and Control Logic CDAC Buffer 5kΩ Internal +2.5V Ref Comparator Output Latches and Three State Drivers R/C CS BUSY Parallel Data Bus 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.
