The AD9644 is a 14-bit, 80 MSPS/155 MSPS, 1.8 V dual serial output analog-to-digital converter (ADC). The AD9644 features low power, high resolution, high accuracy, high sampling rate and low noise, and is suitable for applications such as communications, radar, digital broadcasting and other high-performance applications.
The AD9644 is a dual‑channel, 14‑bit analog‑to‑digital converter designed for high‑speed communications and software‑defined radio applications. It provides serial JESD204A outputs, flexible input ranges, built‑in self‑test, and power‑down modes, all in a 48‑lead LFCSP package that operates from –40 °C to +85 °C.
The datasheet details electrical specifications such as 14‑bit resolution, up to 155 MSPS sampling, 1.8 V supply, 423 mW (80 MSPS) to 567 mW (155 MSPS) power consumption, and extensive pin‑out and timing information. Application notes and ordering guides are also included.
| Power Consumption (155 MSPS, sine wave) | 567 mW typical |
