The DAC8718 is a low-power, octal, 16-bit digital-to-analog converter DAC. With a 5V reference, the output can either be a bipolar ±15V voltage when operating from dual ±15.5V or higher power supplies, or a unipolar 0V to +30V voltage when operating from a +30.5V or higher power supply. With a 5.5V reference, the output can either be a bipolar ±16.5V voltage when operating from dual ±17V or higher power supplies, or a unipolar 0V to +33V voltage when operating from a +33.5V or higher power supply. This DAC provides low-power operation, good linearity, and low glitch over the specified temperature range of –40°C to +105°C. This device is trimmed in manufacturing and has very low zero-code and gain error. In addition, system level calibration can be performed to achieve ±1 LSB bipolar zero/full-scale error with bipolar supplies, or ±1 LSB zero code/full-scale error with a unipolar supply, over the entire signal chain. The output range can be offset by using the DAC offset register.
The DAC8718 features a standard, high-speed serial peripheral interface SPI that operates at up to 50MHz and is 1.8V, 3V, and 5V logic compatible, to communicate with a DSP or microprocessor. The input data of the device are double-buffered. An asynchronous load input LDAC transfers data from the DAC data register to the DAC latch. The asynchronous CLR input sets the output of all eight DACs to AGND. The VMON pin is a monitor output that connects to the individual analog outputs, the offset DAC, the reference buffer outputs, and two external inputs through a multiplexer mux.
The DAC8718 is pin-to-pin and function-compatible with the DAC8218 14-bit and the DAC7718 12-bit.
