The AD9203 is a 10-Bit, 40 MSPS, 3 V, 74 mW A/D converter. It features low power consumption, high dynamic range, and adjustable power consumption. It is suitable for applications such as CCD imaging, video, portable instrumentation, IF and baseband communications, cable modems and medical ultrasound.
The AD9203 is a monolithic, single‑supply 10‑bit ADC that operates up to 40 MSPS while consuming only 74 mW at a 3 V supply. It features an adjustable input range (1 V‑2 V p‑p differential or single‑ended), an on‑chip voltage reference, power‑down mode (0.65 mW), and an out‑of‑range indicator. The device is supplied in a 28‑lead TSSOP package and is rated for industrial temperature ranges.
The datasheet provides detailed specifications, pin configurations, absolute maximum ratings, typical performance curves, and application notes such as CCD imaging, video, portable instrumentation, and medical ultrasound. It also includes terminology definitions and a revision history for reference.
