The MAX5858 dual, 10-bit, 300Msps digital-to-analog con-
verter (DAC) provides superior dynamic performance in
wideband communication systems. The MAX5858 inte-
grates 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 power-supply operating range of 2.7V to 3.3V.
The analog outputs support a compliance voltage of -1.0V
to +1.25V.
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 sup-
ply. 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 spec-
ified for the extended (-40°C to +85°C) temperature range.
