The MAX5853 is a dual, 10-bit, 80Msps digital-to-analog converter (DAC) that provides superior dynamic performance in wideband communication systems. The device integrates two 10-bit DAC cores and a 1.24V reference. It supports single-ended and differential modes of operation. The MAX5853 maintains dynamic performance over the entire 2.7V to 3.6V power-supply operating range. The analog outputs support a -1.0V to +1.25V compliance voltage. It can also operate in interleave data mode to reduce the I/O pin count. The MAX5853 features digital control of channel gain matching to within ±0.4dB in sixteen 0.05dB steps, improving sideband suppression in analog quadrature modulation applications. It includes an on-chip 1.24V bandgap reference with a control amplifier for external full-scale adjustments of both channels through a single resistor. The internal reference can be disabled, and an external reference can be applied for high-accuracy applications. The MAX5853 has full-scale current outputs of 2mA to 20mA and operates from a 2.7V to 3.6V single supply. It supports three modes of power-control operation: normal, low-power standby, and complete power-down. In power-down mode, the operating current is reduced to 1µA. The MAX5853 is packaged in a 40-pin thin QFN with exposed paddle (EP) and is specified for the extended (-40°C to +85°C) temperature range.
The MAX5853 dual, 10‑bit, 80 Msps digital‑to‑analog converter provides high‑speed current‑output performance for wideband communication systems. It integrates two DAC cores, an on‑chip 1.24 V bandgap reference, and supports both single‑ended and differential operation.
The device is supplied in a 40‑pin thin QFN package, operates from 2.7 V to 3.6 V, and offers a full‑scale output current of 2 mA to 20 mA. Power‑down mode reduces the current to 1 µA, and the part is rated for –40 °C to +85 °C operation.
