14-bit SAR ADC with 800 kSPS throughput
The LTC1419IG#PBF is a 14-bit successive-approximation-register (SAR) ADC that samples at 800 kSPS. At this rate the Nyquist limit is 400 kHz — the converter captures the full amplitude of a 400 kHz sine wave without aliasing, so it fits applications such as high-speed data acquisition, vibration analysis, and industrial instrumentation where the signal bandwidth stays below that ceiling. The input stage accepts either a differential or single-ended signal, selected by the user. Differential mode rejects common-mode noise picked up on long cable runs — a real advantage when the ADC sits meters from the sensor in a factory-floor panel. It requires split supplies: ±5 V for the analog core and a separate 5 V digital rail. The analog supply rails set the input range; the digital rail powers the parallel output bus. A board designer should plan for a clean ±5 V analog rail and a 5 V digital rail, with the analog and digital grounds tied at the converter to avoid coupling switching noise into the reference.
Industrial temperature range and package
Packaged in Bulk (not tape-and-reel), so it ships in tubes or trays. For a prototype run or a low-volume production line this is fine; for a high-volume pick-and-place line you will want to confirm the feeder compatibility or request a reeled variant.
