Texas Instruments Digital-to-Analog Converter: DAC7568 / DAC8168 / DAC8568
The Texas Instruments DAC7568, DAC8168, and DAC8568 are low-power, voltage-output, eight-channel, 12-, 14-, and 16-bit digital-to-analog converters (DACs) that include a 2.5V, 2ppm/°C internal reference and a full-scale output voltage range of 2.5V or 5V. These TI devices minimize code-to-code transient voltages (glitches) and provide high relative accuracy. Each TI DAC´s internal reference has an initial accuracy of 0.004% and can source up to 20mA at the VrefIN/VrefOUT pin. The TI DAC7568, DAC8168, and DAC8568 incorporate a power-on reset circuit that ensures the DAC output powers up at either zero scale or midscale until a valid code is written to the device.
