The MAX5858 dual, 10-bit, 300Msps digital-to-analog converter (DAC) provides superior dynamic performance in wideband communication systems. The MAX5858 integrates two 10-bit DAC cores, 2x/4x programmable digital interpolation filters, and a 1.24V reference. The MAX5858 supports single-ended and differential modes of operation. The MAX5858 dynamic performance is maintained over the entire 2.7V to 3.3V power supply. The analog outputs support a -1.0V to +1.25V compliance voltage.
The 4x/2x programmable interpolation filters feature excellent passband distortion and noise performance. Interpolating filters minimize the design complexity of analog reconstruction filters while lowering data bus and clock speeds of the digital interface. To reduce the I/O pin count, the DAC can also operate in interleave data mode. This allows the MAX5858 to be updated on a single 10-bit bus.
The MAX5858 features digital control of channel gain matching to within ±0.4dB in 16 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 MAX5858 features full-scale current outputs of 2mA to 20mA and operates from a 2.7V to 3.3V 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 MAX5858 is packaged in a 48-pin TQFP with exposed paddle (EP) for enhanced thermal dissipation and is specified for the extended (-40°C to +85°C) temperature range.
