AD5689RTCPZ-EP-RL7

AD5689R-EP is a dual, 16bit nanoDAC+ with SPI interface. This device includes a 2.5V, internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5V (gain = 1) or 5V (gain = 2). This device operates from a single 2.7V to 5.5V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5mV offset error performance. It 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 remains there until a valid write occurs. This device contains a per channel power-down feature that reduces the current consumption of the device to 4μA at 3V while in power-down mode. Application includes optical transceivers, base station power amplifiers, process control (PLC I/O cards), industrial automation, data acquisition systems.

• Relative accuracy is ±1LSB typical at (gain = 2, VDD = 2.7V to 5.5V)
• Low drift 2.5V reference 4ppm/°C typical
• Total unadjusted error is ±0.01% of FSR typ at (external reference, gain = 2)
• Offset error is +0.1mV typical at (VDD = 2.7 to 5.5V, 1.62V ≤ VLOGIC ≤ 5.5V)
• High drive capability 15mA, 0.5V from supply rails
• User-selectable gain of 1 or 2 (GAIN pin), reset to zero scale or midscale (RSTSEL pin)
• 1.8V logic compatibility, 50MHz SPI with readback or daisy chain
• 0.5nV-sec typical low glitch, 3.3mW at 3V low power
• 2.7V to 5.5V power supply range
• 16 lead LFCSP-WQ package, temperature range from -55°C to +125°C
