DAC8565IAPW

Product Summary

The DAC8565IAPW is a low-power, voltage-output, four-channel, 16-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/℃ internal reference (enabled by default), giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.004% and can source up to 20mA at the VREFH/VREFOUT pin. The DAC8565IAPW is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The DAC8565IAPW use a versatile 3-wire serial interface that operates at clock rates up to 50MHz. It is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces. The applications of the DAC8565IAPW include Portable Instrumentation, Closed-Loop Servo-Control, Process Control, PLCs, Data Acquisition Systems, Programmable Attenuation and PC Peripherals.
