AD9203 is a 10-bit, 40 MSPS, 3 V, 74 mW A/D converter that can be used for CCD imaging, video, portable instrumentation, IF and baseband communications, cable modems and medical ultrasound applications.
The AD9203 from Analog Devices is a monolithic, single‑supply, 10‑bit analog‑to‑digital converter capable of 40 MSPS sampling. It features an on‑chip voltage reference, adjustable input range (1 V‑2 V p‑p differential), and programmable power consumption for low‑power operation.
The device is offered in a 28‑lead TSSOP package, operates from 2.7 V to 3.6 V, and provides high‑performance metrics such as up to 9.55 ENOB at 20 MHz, 0.65 mW standby power, and built‑in clamp functionality for video signal restoration. Typical applications include CCD imaging, video, portable instrumentation, IF and baseband communications, cable modems, and medical ultrasound.
| Resolution | 10 Bits |
|---|---|
| Maximum conversion rate | 40 MSPS |
| Typical power consumption (40 MSPS, 3 V) | 74 mW |
| Standby power consumption | 0.65 mW |
| Input voltage range (differential) | 1 V to 2 V p‑p |
| Supply voltage range | 2.7 V to 3.6 V |
The AD9203 consumes 74 mW when operated at 3 V supply and 40 MSPS.
The input voltage range is adjustable between 1 V and 2 V peak‑to‑peak differential.
At 20 MHz input frequency the AD9203 provides an ENOB of 9.55 bits.
