LTC1852/LTC1853 are 10-bit/12-bit, 400ksps, low power, sampling ADCs.
The LTC1852 and LTC1853 are 8‑channel analog‑to‑digital converters offering 10‑bit (LTC1852) or 12‑bit (LTC1853) resolution. They feature a flexible multiplexer, selectable gain ranges, unipolar or bipolar operation, and a programmable sequencer. Low power consumption (as low as 3 mW at 250 kS/s) and a wide supply range (2.7 V‑5.5 V) make them suitable for high‑speed data acquisition, test and measurement, imaging, telecommunications, industrial process control, and spectrum analysis.
The document provides detailed specifications, absolute maximum ratings, pin functions, timing diagrams, and typical application circuits. It also includes package information for the 48‑lead plastic TSSOP and reference design notes for interfacing with microcontrollers and external reference sources.
