This is the datasheet of AD7677, AD7677 is a 16-bit, 1 LSB INL, 1 MSPS differential ADC.
The AD7677 is a 16‑bit, 1 MSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It provides both serial and parallel data interfaces, selectable 8‑bit or 16‑bit parallel modes, and three operating modes (Warp, Normal, Impulse) for high‑speed, standard, or low‑power applications.
Key specifications include 16‑bit resolution with no missing codes, 1 LSB INL, typical power dissipation of 115 mW (7 µW in power‑down), differential input range of ±2.5 V, SNR of 94 dB (typical at 45 kHz), and THD of –110 dB. The device is offered in 48‑lead LQFP and 48‑lead LFCSP packages and is rated for –40 °C to +85 °C operation.
