General Description
The MAX5858A dual, 10-bit, 300Msps digital-to-analog
converter (DAC) provides superior dynamic performance
in wideband communication systems. The MAX5858A
integrates two 10-bit DAC cores, 4x/2x/1x programmable
digital interpolation filters, phase-lock loop (PLL) clock
multiplier, and a 1.24V reference. The MAX5858A sup-
ports single-ended and differential modes of operation.
The MAX5858A 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/1x programmable interpolation filters feature
excellent passband distortion and noise performance.
Interpolating filters minimize the design complexity of
analog reconstruction filters while lowering the data bus
and the clock speeds of the digital interface. The PLL
multiplier generates all internal, synchronized high-
speed clock signals for interpolating filter operation and
DAC core conversion. The internal PLL helps minimize
system complexity and lower cost. To reduce the I/O pin
count, the DAC can also operate in interleave data
mode. This allows the MAX5858A to be updated on a
single 10-bit bus.
The MAX5858A 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 ref-
erence can be disabled and an external reference can
be applied for high-accuracy applications.
The MAX5858A 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-con-
trol operation: normal, low-power standby, and com-
plete power-down. In power-down mode, the operating
current is reduced to 1A.
The MAX5858A 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) opera-
ting temperature range.
