The AD7888 is a high-speed, low-power 12-bit ADC that operates from a single 2.7V to 5.25V power supply. It has a throughput rate of 125 kSPS and features eight single-ended analog inputs.
The AD7888 is a high speed, low power, 12‑bit ADC that operates from a single 2.7 V to 5.25 V supply and provides up to 125 kSPS throughput. It includes an on‑chip 2.5 V reference, eight single‑ended inputs, and a versatile serial interface (SPI/QSPI/MICROWIRE/DSP). The device is offered in 16‑lead narrow SOIC and TSSOP packages.
Key features include flexible power‑management modes (normal, standby, shutdown), a shutdown current as low as 2 pA, and a full‑scale bandwidth of 2.5 MHz. Detailed pin configurations, timing specifications, and application hints are provided for easy integration into battery‑powered, instrumentation, and high‑speed modem systems.
