The AD9283 is an 8-bit monolithic sampling analog-to-digital converter with an on-chip track-and-hold circuit and is optimized for low cost, low power, small size, and ease of use. The product operates at a 100 MSPS conversion rate, with outstanding dynamic performance over its full operating range. The ADC requires only a single 3.0 V (2.7 V to 3.6 V) power supply and an encode clock for full performance operation. No external reference is needed.
The AD9283 is an 8‑bit monolithic sampling ADC optimized for low cost, low power, and small size. It operates at up to 100 MSPS, offers a 475 MHz analog bandwidth, and includes an on‑chip reference and track‑and‑hold circuit. The device runs from a single 3 V supply (2.7 V‑3.6 V) and can enter a power‑down mode consuming only 4.2 mW.
The datasheet provides full electrical specifications, pin configurations, timing diagrams, and performance graphs. It also lists typical applications such as battery‑powered instruments, hand‑held scopemeters, and low‑cost digital oscilloscopes, and includes mechanical dimensions for the 20‑lead SSOP package.
