16-Bit High-Speed Low Noise Voltage Output DAC (Rev. A)
Texas Instruments
Description
DAC8581 is a 16-bit, high-speed, low-noise DAC operating from dual ±5-V power supplies. DAC8581 is monotonic, has exceptionally low noise and excep- tionally low glitch. The DAC8581’s high-performance, rail-to-rail output buffer is capable of settling within 0.65µs 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 combines DAC8581 perform- ance with an on-chip, 16X over-sampling digital filter. The DAC8581 is specified over –40°C to 85°C tem- perature range.
