The MAX5852 dual, 8-bit, 165Msps digital-to-analog
converter (DAC) provides superior dynamic performance
in wideband communication systems. The device integrates
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 onchip
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 MAX5852 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
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 versions
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 information.
