DAC8822QBDBT

TEXAS INSTRUMENTS  DAC8822QBDBT  芯片, 数模转换器

The DAC8822 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 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. The DAC8822 is packaged in a space-saving TSSOP-38 package and has an industry-standard pinout. The device is specified from -40°C to +125°C.
