GENERAL DESCRIPTION
The AD5317R, a member of the nanoDAC® family, is a low
power, quad, 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 AD5317R 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
4 µA at 3 V while in power-down mode.
The AD5317R employs a versatile SPI interface that operates at
clock rates up to 50 MHz and contains a VLOGIC pin intended for
1.8 V/3 V/5 V logic.
