This document introduces the features and characteristics of AD9283 8-Bit, 50 MSPS/80 MSPS/100 MSPS 3 V A/D Converter, including low power consumption, 475 MHz Analog Bandwidth, SNR = 46.5 dB @ 41 MHz at 100 MSPS, 1 V p-p Analog Input Range, Single 3.0 V Supply Operation (2.7 V–3.6 V), Power-Down Mode: 4.2 mW, etc.
The AD9283 is an 8‑bit monolithic sampling ADC with an on‑chip track‑and‑hold circuit, optimized for low cost, low power, and small size. It operates at a 100 MSPS conversion rate and requires only a single 3.0 V supply (2.7 V–3.6 V) and an encode clock. Digital outputs are TTL/CMOS compatible and a separate output supply pin supports 2.5 V or 3.3 V logic levels.
The device is supplied in a 20‑lead SSOP package for industrial temperature range (‑40 °C to +85 °C). Key performance figures include 46.5 dB SNR at 41 MHz, 90 mW power dissipation at full speed, and a power‑down mode that reduces consumption to 4.2 mW. The datasheet provides detailed specifications, pin descriptions, timing diagrams, and an evaluation‑board bill of materials.
