四通道16位/ 14位/ 12位属于nanoDAC Quad 16-/14-/12-Bit nanoDAC
Product Details
The AD5695R is a low power, quad, 14-bit buffered voltage output DAC. The device includes a 2.5 V, 2 ppm/°C internal reference enabled by default and a gain select pin giving a full-scale output of 2.5 V gain = 1 or 5 V gain = 2. The device operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.
The AD5695R also incorporates 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 AD5695R uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz, and includes a VLOGIC pin intended for 1.8 V/3 V/5 V logic.
