The AD7888 is a high-speed, low-power, 12-bit ADC that operates from a single 2.7 V to 5.25 V power supply. The AD7888 is capable of a 125 kSPS throughput rate. The input track-and-hold acquires a signal in 500 ns and features a single-ended sampling scheme. The AD7888 contains eight single-ended analog inputs, AIN1 through AIN8. The analog input voltage range is -0.5V to VDD + 0.5V, and the supply voltage range is 2.7V to 5.25V.
The AD7888 is a high‑speed, low‑power 12‑bit analog‑to‑digital converter that offers eight single‑ended inputs and an on‑chip 2.5 V reference. It operates from a single supply of 2.7 V to 5.25 V and can achieve a maximum throughput of 125 kSPS.
Key features include flexible power‑management modes, a versatile SPI/QSPI/MICROWIRE/DSP‑compatible serial interface, and a compact 16‑lead TSSOP package. The device provides up to 2.5 MHz full‑power bandwidth and includes built‑in ESD protection on the analog inputs.
