The MAX5852 dual, 8-bit, 165Msps 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
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 ref-
erence 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 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 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.
Pin-compatible, lower speed, and higher resolution ver-
sions are also available. Refer to the MAX5853 (10 bit,
80Msps), the MAX5851 (8 bit, 80Msps), and the
MAX5854 (10 bit, 165Msps) data sheets for more infor-
mation. See Table 4.
