ADS7800 is a 12-bit sampling analog-to-digital converter with a sampling rate of 333kHz, and it integrates the internal sample/hold, reference, clock, digital interface, microprocessor control, and three-state output drivers.
The ADS7800 is a 12‑bit successive‑approximation analog‑to‑digital converter offering 333 kS/s sampling rate, bipolar input ranges of +10 V and +5 V, and integrated sample‑hold, reference, and digital interface. It is supplied in 24‑pin DIP or SOIC packages and operates from +5 V with either –12 V or –15 V supplies.
The document includes detailed electrical specifications, pin‑out tables, typical performance curves, theory of operation, control line functions, timing diagrams, and layout recommendations such as grounding, bypassing, and glitch minimization to achieve optimal analog performance.
