The MAX5898 is a 500Msps digital to analog converter (DAC) from Texas Instruments that has a selectable 2x/4x/8x interpolation filter, a digital quadrature modulator, and dual 16-bit high-speed DACs
The MAX5898 programmable DAC integrates dual 16‑bit high‑speed converters, selectable interpolation filters (2×, 4×, 8×), and a digital quadrature modulator on a single chip. It delivers up to 500 Msps update rate, 81 dBc in‑band SFDR at 30 MHz, and 71 dB ACLR for four‑carrier WCDMA at 61.44 MHz, while consuming only 1.2 W.
The device features a standard LVDS interface, 3.3 V SPI configuration port, and offers CMOS‑compatible versions with 12‑, 14‑, and 16‑bit resolutions. Detailed electrical characteristics, pin assignments, and performance graphs are provided for system designers.
