AD7625 is a 16-bit, 6MSPS PulSAR differential ADC from Analog Devices. It features high dynamic range, low power consumption, and is suitable for high dynamic range telecommunications, receivers, digital imaging systems, high-speed data acquisition, spectrum analysis and other applications.
The AD7625 is a 16‑bit, 6 MSPS charge‑redistribution successive‑approximation register (SAR) analog‑to‑digital converter. It features a differential input range of ±4.096 V, an internal 4.096 V reference (or external reference options), and a serial LVDS interface that can operate in self‑clocked or echoed‑clock mode.
The device is supplied in a 32‑lead LFCSP package (5 mm × 5 mm) and is rated for operation from –40 °C to +85 °C. Key specifications include 92 dB typical SNR, 150 mW (140 mW with internal reference) power dissipation, and a 16‑bit resolution with no missing codes.
