The MAX5851 is a high-performance dual 8-bit 80Msps digital-to-analog converter (DAC) that supports single-ended and differential modes of operation. It provides ±0.4dB channel gain matching and an on-chip 1.24V bandgap reference. It supports 2.7V to 3.6V power supply.
The MAX5851 is a dual‑channel, 8‑bit, 80 Msps digital‑to‑analog converter (DAC) that provides high‑speed current‑output conversion for wideband communication systems. It integrates two DAC cores, a 1.24 V bandgap reference, and supports both single‑ended and differential operation with programmable channel‑gain matching.
The device operates from a single 2.7 V to 3.6 V supply, offers a full‑scale output current of 2 mA to 20 mA, and includes low‑power standby and power‑down modes (down to 1 µA). It is packaged in a 40‑pin thin QFN and is rated for –40 °C to +85 °C operation.
