Description

The AD5316R, a member of the nanoDAC® family, is a low power,quad, 10-bit buffered voltage output DAC. The device includesa 2.5 V, 2 ppm/°C internal reference (enabled by default) and again 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 lead lead frame chip scale package (LFCSP) and in a thin shrink small outline package (TSSOP).The AD5316R also incorporates a power-on reset circuit and aRSTSEL pin. The RSTSEL pin ensures that the DAC outputs powerup to zero scale or midscale and remain at that level until a validwrite takes place. The device contains a per channel power-down feature that reduces the current consumption of the device in power-down mode to 4 μA at 3 V.The AD5316R uses a versatile 2-wire serial interface that operatesat clock rates up to 400 kHz and includes a VLOGIC pin intendedfor 1.8 V/3 V/5 V logic.Product Highlights Precision DC Performance.
