12-bit serial I/O A/D converters with self-calibration, multi-channel input and sample and hold function
The ADC12130 family are 12‑bit plus‑sign successive‑approximation A/D converters with configurable input multiplexers. The ADC12130 has a two‑channel MUX, the ADC12132 a 2‑channel MUX, and the ADC12138 an 8‑channel MUX, supporting single‑ended, differential, and pseudo‑differential inputs. They operate from a single 3.3 V or 5 V supply and include self‑calibration to keep linearity errors under ±1 LSB.
The document includes ordering information, package drawings, pin descriptions, absolute maximum ratings, and detailed electrical characteristics such as conversion time, linearity, power consumption, and temperature range. Physical dimensions for each package are also listed.
