Dual, 10-Bit, 165Msps, Current-Output DAC
General Description
Features
The MAX5854 dual, 10-bit, 165Msps 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
MAX5854 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 MAX5854 can operate in interleaved data mode to
reduce the I/O pin count. This allows the converter to
be updated on a single, 10-bit bus.

♦ Programmable Channel Gain Matching
♦ Integrated 1.24V Low-Noise Bandgap Reference
♦ Single-Resistor Gain Control
The MAX5854 features digital control of channel gain
matching to within 0.4dꢀ in siꢁteen 0.05dꢀ steps.
Channel matching improves sideband suppression in
analog quadrature modulation applications. The on-
chip 1.24V bandgap reference includes a control
amplifier that allows eꢁternal full-scale adjustments of
both channels through a single resistor. The internal ref-
erence can be disabled and an eꢁternal reference may
be applied for high-accuracy applications.
♦ Interleaved Data Mode
♦ Single-Ended and Differential Clock Input Modes
♦ Miniature 40-Pin Thin QFN Package, 6mm x 6mm
♦ EV Kit Available—MAX5854 EV Kit
The MAX5854 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.
