An internal • 2mA Full-Scale Current, with V REF = 10V feedback resistor (RFB) provides temperature • Settling Time: 0.5µs tracking for the full-scale output when combined with an external, current-to-voltage (I/V) precision • 14-Bit Monotonic amplifier. • 4-Quadrant Multiplying Reference Inputs A RSTSEL pin allows system reset assertion (RS) to • Reference Bandwidth: 10MHz force all registers to zero code when RSTSEL = '0', • Reference Input: ±18V or to mid-scale code when RSTSEL = '1'. • Reference Dynamics: –105 THD Additionally, an internal power-on reset forces all registers to zero or mid-scale code at power-up, • Midscale or Zero Scale Reset depending on the state of the RSTSEL pin. • Analog Power Supply: +2.7V to +5.5V A parallel interface offers high-speed • TSSOP-38 Package communications. The DAC8805 is packaged in a • Industry-Standard Pin Configuration space-saving TSSOP-38 package and has an • Pin Compatible with the 16-Bit DAC8822 industry-standard pinout. The device is specified from –40 °C to +125°C. • Temperature Range: –40°C to +125°C For a 16-bit, pin-compatible version, see the DAC8822. • Automatic Test Equipment • Instrumentation • Digitally Controlled Calibration • Industrial Control PLCs Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
