AD5317RBCPZ-RL7

AD5317R is a quad 10bit nanoDAC® with I²C interface. This 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 at that level until a valid write takes place. Each part contains a per-channel power-down feature that reduces the current consumption of the device to 4µA at 3V while in power-down mode. This employs a versatile SPI interface that operates at clock rates up to 50MHz and contains a VLOGIC pin intended for 1.8V/3V/5V logic. Application includes digital gain and offset adjustment, programmable attenuators, industrial automation, data acquisition systems.
