The LTC1099 is a high speed microprocessor compatible 8-bit analog-to-digital converter (A/D) from Linear Technology Corporation. It has a conversion rate of 2.5µs and can sample input signals up to 156kHz 5VP-P.
The LTC1099 is a high‑speed, microprocessor‑compatible 8‑bit analog‑to‑digital converter with a built‑in sample‑and‑hold circuit. It offers a conversion time of 2.5 µs, a slew‑rate limit of 2.5 V/µs, and low power consumption (75 mW max). The device features edge‑sensitive timing inputs, three‑state latched outputs, an overflow output for cascading, and a user‑adjustable conversion‑time pin.
The datasheet details key specifications, absolute maximum ratings, pin assignments, timing diagrams for RD and WR‑RD modes, functional block diagrams, package dimensions (20‑lead PDIP and 20‑lead SO), and example applications such as cascading for 9‑bit resolution. Related parts and ordering information are also provided.
