ADC082S021 2 Channel, 200 KSPS, 8-Bit A/D Converter
The ADC082S021 provides two input channels (IN1, IN2) and operates from a single supply of +2.7 V to +5.25 V. It features a successive‑approximation register architecture with an internal track‑and‑hold circuit and supports sample rates from 50 kSPS to 200 kSPS. The device is supplied in an 8‑lead MSOP package and is rated for industrial temperature ranges of –40 °C to +85 °C.
Typical applications include portable systems, remote data acquisition, and instrumentation and control. Power consumption is 1.6 mW at 3 V (typ) and 5.8 mW at 5 V (typ), with a shutdown mode that reduces consumption to sub‑nanowatt levels. Detailed timing diagrams, pin descriptions, and electrical characteristics are provided for system integration.
