DAC8822QCDBTG4 (TEXAS INSTRUMENTS)

The DAC8822QCDBTG4 is a dual 16-bit multiplying Digital-to-analog Converter (DAC) designed to operate from a single 2.7 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 pi allows system reset assertion (RS) to force all registers to zero code when RSTSEL = 0 or to midscale code when RSTSEL = 1. Additionally, an internal power-on reset forces all registers to zero or midscale code at power-up, depending on the state of the RSTSEL pin. A parallel interface offers high-speed communications.
