This datasheet provides detailed information on the ADC10154/ADC10158 10-bit plus sign 4 µs ADCs, including the 4- or 8-channel analog input multiplexers, track/hold function, and a 2.5V band-gap reference.
The ADC10154 and ADC10158 are CMOS 10‑bit plus‑sign successive‑approximation A/D converters featuring configurable 4‑ or 8‑channel analog multiplexers, a track/hold function, and an internal 2.5 V band‑gap reference. They support both unipolar operation with a single +5 V supply and bipolar operation with dual ±5 V supplies, and offer programmable resolution and output data formats.
Key features include a selectable input range (0‑5 V or ±5 V), fast conversion times (as low as 3.2 µs for 8‑bit mode), high sampling rates (up to 166 kHz for 10‑bit plus‑sign mode), and a fully tested design with no missing codes over temperature. The document provides detailed pin descriptions, electrical characteristics, timing diagrams, ordering information, and mechanical dimensions.
