The MAX5894 is a programmable 500Msps dual channel digital-to-analog converter (DAC) with selectable 2x/4x/8x interpolation filter, digital quadrature modulator and dual 14-bit high speed DACs.
The MAX5894 programmable interpolating, modulating dual DAC offers superior dynamic performance for high‑performance wideband, single‑carrier transmit applications. It integrates selectable 2×/4×/8× interpolation filters, a digital quadrature modulator, and dual 14‑bit high‑speed DACs on a single IC.
Key features include an in‑band SFDR of 86 dBc at 30 MHz, 73 dB ACLR for two‑carrier WCDMA at 61.44 MHz, low power consumption of 1.1 W, and standard 1.8 V CMOS/3.3 V tolerant data inputs. The device supports a maximum DAC update rate of 500 Msps and offers programmable gain, offset, and modulation modes.
