DAC8805

BurrĆBrown Products from Texas Instruments DA C8 80 5 DAC8805 SBAS391A – DECEMBER 2006 – REVISED MAY 2007 14-Bit, Dual, Parallel Input, Multiplying Digital-to-Analog Converter FEATURES ±0.5LSB DNL ±0.5LSB INL Low Noise: 12nV/√Hz Low Power: IDD = 1µA per channel at 2.7V 2mA Full-Scale Current, with VREF = 10V Settling Time: 0.5µs 14-Bit Monotonic 4-Quadrant Multiplying Reference Inputs Reference Bandwidth: 10MHz Reference Input: ±18V Reference Dynamics: –105 THD Midscale or Zero Scale Reset Analog Power Supply: +2.7V to +5.5V TSSOP-38 Package Industry-Standard Pin Configuration Pin Compatible with the 16-Bit DAC8822 Temperature Range: –40°C to +125°C DESCRIPTION The DAC8805 dual, multiplying digital-to-analog converter (DAC) is designed to operate from a single 2.7V to 5.5V supply. The applied external reference input voltage VREF determines the full-scale output current. An internal feedback resistor (RFB) provides temperature tracking for the full-scale output when combined with an external, current-to-voltage (I/V) precision amplifier. A RSTSEL pin allows system reset assertion (RS) to force all registers to zero code when RSTSEL = '0', or to mid-scale code when RSTSEL = '1'. Additionally, an internal power-on reset forces all registers to zero or mid-scale code at power-up, depending on the state of the RSTSEL pin. A parallel interface offers high-speed communications. The DAC8805 is packaged in a space-saving TSSOP-38 packag...
