AD5313RBCPZ-RL7

双通道， 10位属于nanoDAC与2 PPM /℃参考， SPI接口 Dual, 10-Bit nanoDAC with 2 ppm/C Reference, SPI Interface

Product Details

The AD5313R, a member of the _nano_DAC® family, is a low power, dual, 10-bit buffered voltage output digital-to-analog converter 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 AD5313R 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 package and a TSSOP package.

The AD5313R 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 occurs. The 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 AD5313R employs a versatile serial peripheral interface SPI that operates at clock rates up to 50 MHz, and the device contains a VLOGIC pin that is intended for 1.8 V/3 V/5 V logic.
