Low power DACs are highly accurate with voltage-output

Texas Instruments DACx0501 DACs provide 16-bit (DAC80501), 14-bit (DAC70501), and 12-bit (DAC60501) options. The DACs are highly accurate, low-power devices with voltage-output. The DACs are specified monotonic by design and provide linearity of <1LSB. The devices include a 2.5V, 5ppm/C internal reference, supplying full-scale output voltage ranges of 1.25V, 2.5V, or 5V.

The device includes a power-on-reset circuit assuring the DAC output powers up at zero scale or midscale and stays at that scale until a valid code is written to the device. The devices consume a low current of 1mA and incorporate a power-down feature that lessens current consumption to typically 15µA at 5V. The device's digital interface can be configured to SPI or I2C mode utilising the SPI2C pin. In SPI mode, the device employs a versatile three-wire serial interface that operates at clock rates of up to 50MHz. In I2C mode, the DACs operate in standard (100kbps), fast (400kbps), and fast+ (1.0Mbps) modes.

The DACs are provided in small 2mm x 2mm, eight-pin WSON packages, as well as easy-to-assemble ten-pin VSSOP. The devices feature an industrial temperature range of –40C to +125C.

Typical application fields include oscilloscope, semiconductor test, data acquisition. LCD test. analog output module, small cell base station, process analytics, and DC power supply, AC source, electronic load.
