The MAX165 and MAX166 are high‑speed 8‑bit ADCs compatible with microprocessor interfaces. They feature a built‑in 1.23 V bandgap reference, track/hold capability up to 386 mV/µs, and operate from a single +5 V supply. The devices support single‑ended (MAX165) or differential (MAX166) inputs and provide a 50 kHz signal bandwidth.
The datasheet includes pin configurations, ordering information, electrical and timing characteristics, and detailed interface diagrams for slow‑memory, ROM, and asynchronous modes. It also describes offset and full‑scale adjustments, differential input operation, and reference circuitry recommendations.
