Description
Item Description:
The MAX5853 dual, 10-bit, 80Msps digital-to-analog converter (DAC) provides superior dynamic performance in wideband communication systems. The device integrates 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 reference 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 operation: 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.
