AD7816/AD7817/AD7818 is a single-channel and 4-channel, 9s, 10-bit ADC with on-chip temperature sensor
The AD7817 is a 10‑bit analog‑to‑digital converter offering one or four single‑ended analog input channels and an integrated temperature sensor. It operates from a single 2.7 V to 5.5 V supply and includes on‑chip reference, track‑and‑hold, and an over‑temperature indicator.
Key features include a resolution of 0.25 °C for temperature measurement, low‑power operation (as low as 4 µW at 10 SPS), flexible serial interfaces compatible with 8051, SPI, QSPI and National Semiconductor protocols, and a range of package options (SOIC, MSOP, TSSOP). The datasheet provides detailed specifications, timing characteristics, absolute maximum ratings, ordering codes, and pin descriptions.
