AD5689BRUZ-RL7

双通道， 16位/ 12位，属于nanoDAC ，SPI接口 Dual, 16-/12-Bit nanoDAC with SPI Interface

Product Details

The AD5689/AD5687 members of the _nano_DAC+™ family are low power, dual, 16-/12-bit, buffered voltage output digital-to-analog converters DACs. The devices include a gain select pin giving a full-scale output of 2.5 V gain = 1 or 5 V gain = 2. The AD5689/AD5687 operate from a single 2.7 V to 5.5 V supply, are guaranteed monotonic by design, and exhibit less than 0.1% FSR gain error and 1.5 mV offset error performance. Both devices are available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5689/AD5687 also incorporate a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Each part contains a per channel power-down feature that reduces the current consumption of the device to 4 µA at 3 V while in power-down mode.

The AD5689/AD5687 uses a versatile serial peripheral interface that operates at clock rates up to 50 MHz. Both devices contain a VLOGIC pin that is intended for 1.8 V/3 V/5 V logic.
