The MAX5852 dual, 8-bit, 165Msps digital-to-analog converter (DAC) provides superior dynamic performance in wideband communication systems. The device integrates two 8-bit DAC cores, and a 1.24V reference. The MAX5852 supports single-ended and differential modes of operation. The dynamic performance is maintained over the entire 2.7V to 3.6V power-supply operating range. The analog outputs support a -1.0V to +1.25V compliance voltage. The MAX5852 can operate in interleaved data mode to reduce the I/O pin count. This allows the converter to be updated on a single, 8-bit bus. The MAX5852 features digital control of channel gain matching to within ±0.4dB in sixteen 0.05dB steps. Channel matching improves sideband suppression in analog quadrature modulation applications. The on-chip 1.24V bandgap reference includes a control amplifier that allows external full-scale adjustments of both channels through a single resistor. The internal reference can be disabled and an external reference may be applied for high-accuracy applications. The MAX5852 features full-scale current outputs of 2mA to 20mA and operates from a 2.7V to 3.6V single supply. The DAC 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 MAX5852 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 MAX5852 is a dual‑channel, 8‑bit, 165 Msps digital‑to‑analog converter (DAC) that provides superior dynamic performance for wideband communication systems. It integrates two 8‑bit DAC cores, a 1.24 V bandgap reference, and supports both single‑ended and differential operation over a 2.7 V to 3.6 V supply range.
Key features include programmable channel‑gain matching, interleaved data mode to reduce I/O pins, full‑scale output current of 2 mA to 20 mA, and a compact 40‑pin thin QFN package rated for –40 °C to +85 °C. The datasheet also provides detailed electrical characteristics, timing specifications, and application circuits for differential‑to‑single‑ended conversion.
