The AD9203 is a monolithic low power, single supply, 10-bit, 40 MSPS analog-to-digital converter, with an on-chip voltage reference. The AD9203 uses a multistage differential pipeline architecture and guarantees no missing codes over the full operating temperature range.
The AD9203 is a monolithic, low‑power, single‑supply 10‑bit ADC that operates from 2.7 V to 3.6 V and delivers 40 MSPS at a typical power consumption of 74 mW. It features an on‑chip programmable voltage reference, adjustable input range (1 V‑2 V p‑p), and a power‑down mode that reduces consumption to 0.65 mW.
The datasheet provides detailed specifications, pin‑out, absolute maximum ratings, functional block diagram, and typical performance graphs. It lists applications such as CCD imaging, video, portable instrumentation, cable modems, and medical ultrasound.
| Resolution | 10 Bits |
|---|---|
| Maximum Conversion Rate | 40 MSPS |
| Power Consumption (typical, 40 MSPS) | 74 mW |
| Power‑Down (Standby) Power | 0.65 mW |
| Operating Voltage (AVDD) | 2.7 V – 3.6 V |
| Input Voltage Range | 1 V – 2 V p‑p (differential or single‑ended) |
The AD9203 consumes about 74 mW when operating at 40 MSPS with a 3 V supply.
In standby (power‑down) mode the device draws only 0.65 mW.
The converter accepts a differential or single‑ended input range of 1 V to 2 V p‑p.
The AD9203 achieves an ENOB of 9.55 bits at a 20 MHz input frequency.
