The AD9785/AD9787/AD9788 are 12-bit, 14-bit, and 16-bit, high dynamic dual 12-/14-/16-bit 800 MSPS DACs. They feature adjustable analog output, low power, fine complex NCO, multiple chip synchronization interface, etc.
The AD9785, AD9787, and AD9788 are 12‑bit, 14‑bit, and 16‑bit high‑dynamic‑range transmit DACs that operate at a sample rate of 800 MSPS, enabling multicarrier generation up to the Nyquist frequency. They include features such as a low‑power 32‑bit complex NCO, programmable gain and phase compensation, and auxiliary DACs for I/Q gain matching and offset control.
The devices are supplied in a 100‑lead TQFP package, operate from 1.8 V and 3.3 V supplies, and are intended for wireless infrastructure, wideband communications, and direct‑conversion transmit applications. The datasheet provides detailed electrical specifications, pin descriptions, thermal data, and evaluation board information.
