AD9246 is a monolithic 14-bit, 80 MSPS/105 MSPS/125 MSPS, 1.8 V analog-to-digital converter with low power, low noise, high bandwidth and high precision. It is suitable for ultrasound equipment, IF sampling in communications receivers, IS-95, CDMA-One, IMT-2000 and other applications.
The AD9246 is a monolithic, single‑supply 14‑bit ADC offering up to 125 MSPS sampling rates. It features a high‑performance sample‑and‑hold amplifier, on‑chip voltage reference, and a differential pipeline architecture that guarantees no missing codes across the industrial temperature range.
The device is supplied in a 48‑lead LFCSP_VQ package and supports multiple data formats (offset binary, Gray code, two's complement) via a standard serial port interface. Detailed specifications cover DC, AC, digital, and switching performance, along with pin configurations, timing diagrams, and layout recommendations.
| Resolution | 14 bits |
|---|---|
| Maximum Sampling Rate | 125 MSPS (DCS enabled) |
| Supply Voltage (Analog) | 1.8 V (typical) |
