DAC7565,pdf(12-Bit, Quad, Ultr

The DAC7565 is a low-power, voltage-output, four-channel, 12-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/°C internal reference (enabled by default), giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.02% and can source up to 20mA at the V_REFH/V_REFOUT pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The DAC7565 uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz. The interface iscompatible with standard SPI?, QSPI?, Microwire?, and digital signal processor (DSP) interfaces.

The DAC7565 incorporates a power-on-reset circuit that ensures the DAC output powers up at either zero-scale or mid-scale until a valid code is written to the device.
