General Description
The MAX5851 dual, 8-bit, 80Msps, digital-to-analog
converter (DAC) provides superior dynamic performance
in wideband communication systems. The device inte-
grates two 8-bit DAC cores, and a 1.24V reference. The
converter supports single-ended and differential modes
of operation. The MAX5851 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 MAX5851 can also operate in interleave data mode
to reduce the I/O pin count. This allows the converter to
be updated on a single, 8-bit bus.
The MAX5851 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 may
be applied for high-accuracy applications.
The MAX5851 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 opera-
tion: normal, low-power standby, and complete power-
down. In power-down mode, the operating current is
reduced to 1A.
The MAX5851 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.
Pin-compatible, higher speed, and higher resolution
versions are also available. Refer to the MAX5852
(8 bit, 165Msps), the MAX5854 (10 bit, 165Msps), and
the MAX5853 (10 bit, 80Msps) data sheets for more
information. See Table 4.
