DESCRIPTION

The DAC8871 is a 16-bit, single-channel, serial input,

voltage output digital-to-analog converter (DAC). The

output range is determined by the reference voltage, VREFH and VREFL. By properly selecting the reference,

the output can be unipolar or bipolar, and up to ±18V.

The DAC8871 provides excellent linearity (1LSB INL),

low noise, and fast settling (1ms to 1LSB of full scale

output) over the specified temperature range of

–40°C to +105°C. The output is unbuffered, which

reduces the power consumption and the error

introduced by the buffer. This device features a

standard high-speed clock (up to 50MHz), and a 3V or 5V SPI serial interface to communicate with the

DSP or microprocessors. For optimum performance,

a set of Kelvin connections to external reference are

provided.

The DAC8871 is available in a TSSOP-16 package.
