MAX5854

Dual, 10-Bit, 165Msps, Current-Output DAC


Please check latest availability status for a specific part variant.

Description

The MAX5854 dual, 10-bit, 165Msps 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 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.

The MAX5854 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 can be applied for high-accuracy applications.

The MAX5854 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 MAX5854 is packaged in a 40-pin TQFN with exposed paddle (EP) and is specified for the extended (-40°C to +85°C) temperature range.

Pin-compatible, lower speed, and lower resolution versions are also available. Refer to the MAX5853 (10-bit, 80Msps), the MAX5852 (8-bit, 165Msps), and the MAX5851 (8-bit, 80Msps) data sheets for more information. See Table 4 at the end of the data sheet.
