These converters provide excellent linearity (1LSB INL), lowglitch, low noise, and fast settling time (1µs to 1/2 LSB of full-scale output) over the specifiedtemperature range of –40°C to +85°C. The output is unbuffered, which reduces the powerconsumption and the error introduced by the output buffer amplifier.VREFCSSCLKSDIDAC8830SerialInterfaceDGNDVDDInputRegisterDAC8830 functional block diagram.DACDAC LatchVOUTAGNDHighest Accuracy and Industrial Bipolar Output DACDAC8871Get datasheets at: www.ti.com/sc/device/DAC8871Key Features• Resolution: 16-bit• Output voltage: ±18V• High accuracy: ±1LSB INL (max)• Low noise: 10nV/ Hz• Settling time: 1µs to 1LSB• Fast SPI interface, up to 50MHz• Very low power• Packaging: TSSOP-16Applications• Portable equipment• ATE• Industrial process control• Data acquisition systems• Optical networkingThe DAC8871 is a single, serial-input, voltage-output DAC operating from up to a dual ±18Vsupply. The output is unbuffered, which reduces the power consumption and the errorintroduced by the output buffer amplifier. It features a standard high-speed 3V or 5V SPI serialinterface with clock speeds up to 50MHz. For optimum performance, a set of Kelvin connectionsto the external reference is provided.RSTSELRSTLDACCSSCLKSDIAVSS AVDDControlLogicDVDDSerialInterfaceDGND VREFH–S VREFH–F VREFL–SInterface DataRegisterDACDAC LatchVOUTAGNDDAC8871DAC8871 functional block diagram.Amplifier and Data Converter Selection Guide Texas Instruments 3Q 2007
