Analog Devices AD7858/AD7858L Sampling ADC Datasheet
The AD7858 and AD7858L are high‑speed, low‑power 12‑bit analog‑to‑digital converters that operate from a single 3 V to 5.5 V supply. The AD7858 is optimized for speed (200 kSPS) while the AD785L version targets low power consumption.
The device offers eight single‑ended or four pseudo‑differential inputs, flexible serial interfaces (SPI, QSPI, 8051), automatic self‑calibration on power‑up, and multiple power‑down modes. It is available in 24‑lead DIP, SOIC, and SSOP packages.
