The MAX5853 dual, 10-bit, 80Msps digital-to-analog
converter (DAC) provides superior dynamic performance
in wideband communication systems. The device inte-
grates two 10-bit DAC cores, and a 1.24V reference. The
converter supports single-ended and differential modes
of operation. The MAX5853 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 MAX5853 can also operate in interleave data mode
to reduce the I/O pin count. This allows the converter to
be updated on a single, 10-bit bus.
The MAX5853 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 MAX5853 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 1µA.
The MAX5853 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 lower resolution
versions are also available. Refer to the MAX5854
(10-bit, 165Msps), the MAX5852** (8-bit, 165Msps), and
the MAX5851** (8-bit, 80Msps) data sheets for more
information. See
19-3196; Rev 0; 2/04
