The DAC8581 is monotonic, and has exceptionally low noise and exceptionally low glitch. The DAC8581 high-performance, bipolar output buffer is capable of settling within 0.65 μs for a 10-V step. Small-signal settling time is well under 0.3 μs, supporting data update rates up to 3 MSPS. A power-on-reset circuit sets the output at midscale voltage on power up. The DAC8581 is simple to use, with a single external reference and a standard 3-wire SPI interface that allows clock rates up to 50 MHz. Also see the DAC8580, a member of the same family. The DAC8580 bines DAC8581 performance with an on-chip, 16x over-sampling digital filter. The DAC8581 is specified over the - 40°C to +85°C temperature range. space FUNCTIONAL BLOCK DIAGRAM OF DAC8581 AVDD AVSS DVDD VREF SDIN SCLK CS Serial Interface Shift Register DAC...
