The • ±5-V Dual Power Supply DAC8581 is monotonic, and has exceptionally low • Single External Reference noise and exceptionally low glitch. The DAC8581 high-performance, bipolar output buffer is capable of • Power-On Reset to Midscale settling within 0.65 μs for a 10-V step. Small-signal • 3-MSPS Update Rate settling time is well under 0.3 μs, supporting data • SPI™ Interface, Up to 50 MHz update rates up to 3 MSPS. A power-on-reset circuit sets the output at midscale voltage on power up. • 1.8-V–5-V Logic Compatible • Twos Complement Data Format The DAC8581 is simple to use, with a single external reference and a standard 3-wire SPI interface that • Hardware Reset to Midscale allows clock rates up to 50 MHz. • TSSOP-16 Package Also see the DAC8580, a member of the same family. The DAC8580 combines 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 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 SPI is a trademark of Motorola. 3 All other trademarks are the property of their respective owners.
