AD5338R:  Dual 10-Bit nanoDAC® with 2 ppm/°C Reference, I2C Interface

Product Details

Product Status:Recommended for New Designs

The AD5338R, a member of the nanoDAC® family is a low power, dual, 10-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 AD5338R 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 AD5338R 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.
