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.
