Analog Devices AD7898 Datasheet
The AD7898 ADC provides 12‑bit resolution with a maximum throughput of 220 kSPS. It operates from a single 5 V supply and offers two input‑range options: +10 V (AD7898‑10) and +2.5 V (AD7898‑3). The device includes an on‑chip track/hold amplifier, a flexible three‑wire serial interface, and a power‑down mode for portable applications.
The datasheet details electrical specifications, timing parameters, absolute maximum ratings, pin functions, and ordering information. It also includes performance graphs such as SINAD, PSRR, and effective number of bits versus input frequency.
